How quantum can enhance machine learning in finance

Source: Finance Derivative

William Clements, Head of Machine Learning, ORCA Computing

Quantum computing is a rapidly developing field at the intersection of physics and computing. Armed with the ability to solve certain types of problems exponentially faster than its classical counterparts, it has the potential for impact in a wide range of industries, including finance.

One area that is showing promise in finance is quantum machine learning (QML). This combines the principles of quantum computing with advanced machine learning algorithms to help financial organisations improve generative modelling, analyse large volumes of data, and make more informed decisions. While they promise to solve complex financial problems more efficiently and accurately than classical approaches, the applications are still at an exploratory stage. Potential uses include creating synthetic data for generative modelling and optimising investment strategies.

Generative modelling to create synthetic data

By leveraging advanced machine learning techniques, generative models facilitate the creation of synthetic data, which can be used to augment limited datasets, enhance privacy protection, and develop robust trading strategies. Creating synthetic data is also essential to train and evaluate machine learning models in scenarios where real data may be scarce, sensitive, or difficult to obtain. To support innovation in the financial industry, the financial conduct authority (FCA) provides a sandbox environment with high-quality synthetic data for organisations to use. The process of creating synthetic data involves leveraging techniques such as generative adversarial networks (GANs), which consist of two neural networks: a generator and a discriminator. GANs are designed to generate new data samples that resemble a given training dataset. The generator network learns to produce synthetic data, while the discriminator network learns to distinguish between real data from the training set and the synthetic data generated by the generator.

QML holds the potential to enhance the creation of synthetic data for generative modelling and generate realistic and diverse datasets that mimic the characteristics of real financial data. By exploiting quantum principles like superposition and entanglement, these algorithms could capture complex patterns, and produce high-dimensional synthetic data samples. This advancement could open new avenues for training novel generative models such as hybrid quantum/classical GANs, improving their fidelity, and enabling the development of more realistic and diverse synthetic datasets for various applications.

Improving portfolio optimisation

Machine learning is a powerful technology that can be used to improve the performance of portfolios, from identifying factors that predict future returns to constructing portfolios that are diversified and risk-adjusted and rebalancing portfolios on a regular basis. By leveraging advanced algorithms and data analysis techniques to enhance risk assessment, asset selection, portfolio rebalancing, and market prediction, investors can make more informed decisions, improve portfolio performance, and adapt to the dynamic nature of financial markets.

QML is emerging as a useful tool to improve machine learning, as it provides new methods of learning relationships within data. This helps traditional machine learning algorithms process large-scale complex datasets, enabling more comprehensive and accurate portfolio optimisation. It can also assist in solving the combinatorial explosion problem commonly encountered in portfolio optimisation. As the number of assets and possible portfolio combinations grows exponentially, classical computing methods face limitations in exploring all possible solutions. QML algorithms have the potential to come up with better solutions in some cases. This could potentially lead to more sophisticated portfolio construction strategies that consider a broader range of factors, resulting in improved risk-adjusted returns.

Working towards a quantum future

The convergence of quantum computing and machine learning holds the potential to accelerate innovation in the financial industry through its ability to create synthetic data for generative modelling, process significant amounts of data and perform some complex calculations quickly. Despite the foreseeable benefits, practical implementation is still in its early stages. The field requires further research, development, and refinement to overcome challenges such as scalability, but there is an expectation from the quantum industry to demonstrate narrow advantage over classical approaches in the relative near-term. For their part, financial services organisations are actively exploring and investing in QML to enhance their operations, improve decision-making, unlock new insights, and gain a competitive edge over the longer term.

As the field progresses, continued collaborations between experts in quantum computing, machine learning, and financial organisations will be crucial to drive innovation and overcome the current challenges. Even though the road ahead may be complex, the possibilities are endless, and the impact on finance holds the promise of changing how we understand, predict, and manage financial systems.

When something personal fills an important gap in the market 

by Cécile Mazuet-Eller, founder of NameSwitch

There aren’t many business ideas that go from a personal experience to filling an important gap in the market. However, this is certainly the case for NameSwitch, the UK’s pioneering and only name changing support service launched in 2018. But what inspired its inception and what challenges did it face? Here, Cécile Mazuet-Eller, the founder of the company, in its seventh year, explains.

My entrepreneurial journey is a bit unusual in that it started from my own experience of going through a divorce, which became a pivotal turning point for me not only emotionally, but practically too. I wanted to remove my married name, and I had a visceral reason to do so as I really didn’t want to keep it. Feeling extremely frustrated at still receiving letters and official documents featuring my previous name, I was desperate to change it but like for so many people it became a stop-start, arduous task.

Once I started the process, I realised it was taking up far too much time I didn’t have; being a single mum to two young children and working full-time is no mean feat, so when I embarked on the name changing process I realised it wasn’t going to be easy.  Searching for a solution to help, all I came up with was a service covering the US and Canada, but nothing that worked for the UK, so in the end, I spent a whole year to get everything changed that had to be, which proved long and stressful to say the least.

Nurturing the idea

In the early days I was fortunate enough to be surrounded by positive people who had good contacts, and who saw the viability of my idea. Living in a small community filled with intelligent and well-rounded people, I wasn’t short of encouragement from them and friends, who recognised as well as I did there was a definite gap in the market. Working with a web development team in Serbia which was also recommended, I enlisted additional help from a university student on some research.

I always wanted to run my own business, and there were several reasons why I needed to embark on something new. As the only breadwinner in the house, there were mounting bills while balancing the demands of motherhood and other financial responsibilities. Cash was limited but what little I had was used carefully which I put into the business.

In the early stages, which included the development of the unique technology that underpins the service, I carved pockets of time at night and on weekends to create a strong foundation for the business. Creating something completely from scratch was like a form of healing, which is why it was and remains such a personal project.

Mulling over the idea for at least two years following the original lightbulb moment, the business was registered in 2015, with time needed for building the robust platform in order to  create a viable product. Drawing on my previous experience, I investigated overseas equivalents, financials and marketing intelligence ensuring there was a genuine need for the service in the UK. Fortunately enough I was able to share my plans with my employer at the time, who turned out to be my biggest supporters, becoming my first paying customer who purchased a NameSwitch for his ex-wife, who was getting married to someone else!

With a career in telecommunications and a degree in marketing, I was already used to hard work and having the support and encouragement from my telecoms team was extremely helpful.   

Support and coaching

Coaching was an important element of the start-up process, obtained through a wider network and some financial support from family,  with no other funding or investment being available.

The challenges

Presented with certain obstacles like all businesses are, there was a lot to juggle and at times it felt like too much but I managed to navigate the complexities involved. When Covid hit that was a huge set-back, given that our biggest target market was and still is, newly-weds. With all weddings being banned, it hit NameSwitch hard, but our saving grace were the people who used the time to change their name’s in lockdown, by doing something they previously didn’t have time for. Being 100% employed by the business by this stage, it turned into a year of survival and another big challenge.  

In 2022-2023 we concentrated on growth for NameSwitch, when me and my dedicated team were satisfied with the service, it was time to consider investment into PR, advertising and partnerships to increase brand awareness to reach the revenues that were needed.

In 2022-2024, it was forecast that 285,000 – 415,000 weddings will take place resulting from the pandemic, which has reflected well on the business in recent years. And amidst the trials and tribulations it’s proved to be both exhilarating and exhausting in equal measure.

With hindsight, there are certain things I’d have done differently, such as bringing in a partner early on to put us in a stronger position sooner, and adding more resource  to improve growth, but I know that’s all part of the steep learning curve and something to take with me to projects in the future.

Advice for aspiring entrepreneurs

For anyone contemplating their own entrepreneurial endeavours, I’d recommend to ‘one hundred percent go for it’ – but do not bet the house on it and whatever happens, embrace the journey.

How relationships with work are changing

by Amrit Sandhar (CEO/ Founder, &Evolve)

Since Chris Argyris’s work in the 1960s into the psychological work contract, the assumption’s remained that it’s based on mutual exchange of beliefs and expectations of what employee and employer can expect from each other, given a contract only works with two parties agreeing to it.

But have we seen a shift in the balance of this contract, where the expectations of employees have really changed? Since the industrial revolution, organisations dictated employees’ working arrangements which focused on driving greater productivity and performance. This reflected the imbalance of power, with employees reliant on their organisations to structure working arrangements to drive the best results.

Employees signed up to this psychological contract, despite it representing an imbalance in favour of the employer. However, the pandemic stressed this equilibrium, which has led to many, reevaluating their relationship with their work.

While the pandemic has had a long-term impact on most, affecting everything from education to mental health, it could also be the cause of an evolution that’s changing people’s relationship with work. While organisations were supported through furlough schemes and government grants, employees took responsibility for keeping businesses going, by changing the way they worked. Employees took an unprecedented situation and found ways of dealing with it and since the first time in many years, employees had and took direct ownership of the success of the organisations they worked for – which changed everything.

We’ve seen a seismic shift in how we think about work since the that time, which goes far beyond submitting requests for flexible working. It shows that we’re at the threshold of realising a more balanced psychological work contract, driven by employees, who have different mutually agreed beliefs and expectations in how employees and employers work together.

Gone are the days when employees are only satisfied with financial reward and a nice manager. Gen Z will soon become the largest generation making up our workforce and while money is important to them (as they’re likely to be poorer than previous generations), many want work to be something that complements their life, and not something that only provides financial reward.

Some have said the generation gap is a myth, and before the pandemic this may have been true. But when a generation has experienced such a paradigm shift it brings a different mindset of beliefs and expectations about how work can and should be carried out.

It’s hard to see how anyone could go back to the previous way of working, which should have always focussed on outputs and outcomes rather than hours worked. Other than manufacturing, where it was easy to measure productivity, organisations have become complacent in measuring output and outcomes, with employees paying the price for this ambiguity.

Organisations utilising employee engagement surveys, listening forums, and employee representative initiatives often launch them with the best of intentions, however, the historical underlying imbalance of power towards employers, has prevented a more equitable relationship from forming, despite these initiatives. The strain some organisations are experiencing with mounting pressure to challenge how work is carried out, whether from expecting remote working to questioning if a four-day week would drive greater productivity, shows the shift taking place to the long-standing equilibrium of the psychological work contract.

Future successful organisations will be those that can attract and retain the best talent, and it’s unlikely that the next generation of employees will be willing to relinquish their courage to challenge how work is done.

Employees will seek a greater understanding of exactly what’s required of their role and expect organisations to clearly define measures, to understand how their value and success will be measured, regardless of when, where, and how they choose to work.

Rather than resisting change organisations should consider how they can shape it, by questioning and finding solutions to measuring outputs and productivity, by looking at how they help employees feel respected and valued, and how they help bring the psychological contract, based on a new set of mutually agreed expectations and beliefs to life.

How 5G is enhancing communication in critical sectors

Luke Wilkinson, MD, Mobile Tornado

In critical sectors where high-stakes situations are common, effective communication is non-negotiable. Whether it’s first responders dealing with a crisis or a construction team coordinating a complex project, the ability to share information quickly and reliably can mean the difference between success and failure.

Long-distance communication became feasible in the 1950s when wireless network connectivity was first utilised in mobile radio-telephone systems, often using push-to-talk (PTT) technology. As private companies invested in cellular infrastructure, the networks developed and data speeds improved increasingly. Each major leap forward in mobile network capabilities was classed as a different generation and thus 1G, 2G, 3G, 4G, and now 5G were born.

5G is the fifth generation of wireless technology and has been gradually rolled out since 2019 when the first commercial 5G network was launched. Since then, the deployment of 5G infrastructure has been steadily increasing, with more and more countries and regions around the world adopting this cutting-edge technology.

Its rollout has been particularly significant for critical sectors that rely heavily on push-to-talk over cellular (PTToC) solutions. With 5G, PTToC communications can be carried out with higher bandwidth and speed, resulting in clearer and more seamless conversations, helping to mitigate risks in difficult scenarios within critical sectors.

How is 5G benefiting businesses?

According to Statista, by 2030, half of all connections worldwide are predicted to use 5G technology, increasing from one-tenth in 2022. This showcases the rapid pace at which 5G is becoming the standard in global communication infrastructure.

But what does this mean for businesses? Two of the key improvements under 5G are improved bandwidth and download speeds, facilitating faster and more reliable communication within teams. PTToC solutions can harness the capabilities of 5G and bring the benefits to critical sectors that need it most, whether that’s in public safety, security, or logistics: the use cases are infinite. For example, this could be leveraging 5G’s increased bandwidth to enable larger group calls and screen sharing for effective communication.

Communication between workers in critical industries can be difficult, as often the workforces are made up of lone workers or small groups of individuals in remote locations. PTToC is indispensable in these scenarios for producing quick and secure communication, as well as additional features including real-time location information and the ability to send SOS alerts. PTToC with 5G works effectively in critical sectors, as 5G is designed to be compatible with various network conditions, including 2G and 3G. This ensures that communication remains reliable and efficient even in countries or areas where 5G infrastructure is not fully deployed to keep remote, lone workers safe and secure.

The impact of 5G on critical communications

The International Telecommunication Union has reported that 95 percent of the world’s population can access a mobile broadband network. This opens up a world of new possibilities for PTToC, particularly when harnessing new capabilities for 5G as it’s being rolled out.

One of the most significant improvements brought by 5G is within video communications, which most PTToC solutions now offer. Faster speeds, higher bandwidth, and lower latency enhance the stability and quality of video calls, which are crucial in critical sectors. After all, in industries like public safety, construction, and logistics, the importance of visual information for effective decision-making and situational awareness cannot be overstated. 5G enables the real-time transmission of high-quality video, allowing for effective coordination and response strategies, ultimately improving operational outcomes and safety measures.

Challenges in Adopting 5G in Critical Sectors

While the benefits of 5G are undeniable, the industry faces some challenges in its widespread adoption. Network coverage and interoperability are two key concerns that need to be addressed to ensure communication can keep improving in critical sectors.

According to the International Telecommunication Union, older-generation networks are being phased out in many countries to allow for collaborative 5G standards development across industries. Yet, particularly in lower-income countries in Sub-Saharan Africa, Latin America, and Asia-Pacific, there is a need for infrastructure upgrades and investment to support 5G connectivity. The potential barriers to adoption, including device accessibility, the expense of deploying the new networks, and regulatory issues, must be carefully navigated to help countries make the most out of 5G capabilities within critical sectors and beyond.

However, the rollout of 5G does cause data security concerns for mission-critical communications and operations, as mobile networks present an expanded attack surface. Nonetheless, IT professionals, including PTToC developers, have the means to safeguard remote and lone workers and shield corporate and employee data. Encryption, authentication, remote access, and offline functionality are vital attributes that tackle emerging data threats both on devices and during transmission. Deploying this multi-tiered strategy alongside regular updates substantially diminishes the vulnerabilities associated with exploiting 5G mobile networks and devices within critical sectors.

While the challenges faced by the industry must be addressed, the potential benefits of 5G in enhancing communication and collaboration are undeniable. As the rollout of 5G continues to gain momentum, the benefits of this cutting-edge technology in enhancing communication in critical sectors are becoming increasingly evident. The faster, more reliable, and efficient communication enabled by 5G is crucial for industries that rely on real-time information exchange and decision-making.

Looking ahead, the potential for further advancements and increased adoption of 5G in critical sectors is truly exciting. As the industry continues to address the challenges faced, such as network coverage, interoperability, and data security concerns, we can expect to see even greater integration of this technology across a wide range of mission-critical applications for critical sectors.
