Quantum Computing: The Next Big Thing For Finance By 2024




Quantum computing is a new technology that leverages the laws of quantum physics to perform computations that are exponentially faster and more powerful than classical computers. Quantum computers can revolutionize industries and fields that require significant computing power, such as modeling financial markets, designing new effective medicines and vaccines, empowering artificial intelligence, and creating a new and secure way of communication (quantum Internet).

Quantum computing has the potential to change financial services in many ways, from enhancing cybersecurity and fraud detection to optimizing trading and portfolio management to improving customer service and natural language processing. In this article, we will explore some of the use cases and benefits of quantum computing for financial services, as well as some of the challenges and risks that need to be addressed.

Quantum Computing for Cybersecurity and Fraud Detection


One of the most important applications of quantum computing for financial services is cybersecurity and fraud detection. Quantum computers can crack many of the current encryption algorithms that protect mobile banking, e-commerce, fintech, digital currencies, and Internet information exchange. This poses a serious threat to financial stability and data privacy.



However, quantum computers can also provide a solution to this problem, by enabling quantum cryptography, which is a secure way of transferring quantum information across space. Quantum cryptography is based on the quantum mechanical phenomenon of entanglement, which means that two or more particles can share a quantum state and influence each other, even when they are separated by large distances. This allows for the exchange of a secret key that can encrypt messages in a way that is impossible to eavesdrop or tamper with, even by a quantum computer.



Quantum cryptography can also be combined with post-quantum cryptographic algorithms, which are classical algorithms that are resistant to quantum attacks. This can provide an extra layer of security and resilience for financial institutions.



Another application of quantum computing for cybersecurity and fraud detection is quantum machine learning (QML), which is a branch of artificial intelligence that uses quantum algorithms to learn from data. QML can enhance the performance and accuracy of fraud detection models, by exploiting the parallelism and interference of quantum states. QML can also handle large or unstructured data sets better than classical machine learning, which can help identify patterns and anomalies in financial transactions.

For example, HSBC and Quantinuum, a quantum computing company, have announced a series of exploratory projects that use QML techniques for fraud detection. They will leverage Quantinuum’s software development platform, TKET, which provides qubit routing and circuit optimization techniques for quantum algorithms.



Quantum Computing for Trading and Portfolio Management



Another area where quantum computing can have a significant impact is trading and portfolio management. Quantum computers can enable financial institutions to perform complex calculations and simulations faster and more accurately than classical computers, which can improve decision-making and risk management.



One of the challenges that traders and portfolio managers face is finding the optimal allocation of assets that maximizes returns while minimizing risk. This is known as the portfolio optimization problem, which is a type of optimization problem that involves finding the best solution among many possible ones.



Optimization problems are hard to solve with classical computers because they require exploring a large number of variables and constraints. However, quantum computers can solve optimization problems more efficiently, by using quantum algorithms such as Grover’s algorithm or quantum annealing.



Grover’s algorithm is a quantum algorithm that can find a target element in an unsorted database with quadratic speedup over classical algorithms. Quantum annealing is a quantum technique that uses quantum fluctuations to escape local minima and find the global minimum of a cost function.



Quantum algorithms for optimization can help traders and portfolio managers find the optimal portfolio allocation in real-time, considering market conditions, risk factors, liquidity constraints, transaction costs, and other parameters. This can enhance their performance and profitability.



For example, BBVA and Multiverse Computing, a quantum software company, have collaborated on a project that uses quantum annealing to optimize currency portfolios. They have shown that their approach can reduce portfolio risk by 2% compared to classical methods.



Quantum Computing for Customer Service and Natural Language Processing



A third domain where quantum computing can benefit financial services is customer service and natural language processing (NLP). NLP is a field of artificial intelligence that deals with the interaction between human language and computers. NLP can enable financial institutions to provide better customer service, by understanding and responding to customer queries, requests, and feedback in natural language.



NLP involves various tasks, such as speech recognition, sentiment analysis, text summarization, machine translation, and question answering. These tasks can be challenging for classical computers because they require processing large amounts of linguistic data and capturing the nuances and ambiguities of human language.



Quantum computers can improve NLP tasks, by using quantum algorithms that can process natural language data faster and more accurately than classical algorithms. Quantum algorithms can also leverage quantum phenomena such as superposition and entanglement, which can help capture the semantic and contextual relationships between words and sentences.



For example, HSBC and Quantinuum have also announced a project that explores the potential benefits of quantum natural language processing (QNLP) for HSBC’s business. They will use QNLP techniques to analyze customer feedback and sentiment, as well as to generate natural language responses to customer queries.

Conclusion



Quantum computing is a disruptive technology that will transform financial services by 2024. Quantum computers can provide significant advantages over classical computers in terms of speed, power, and accuracy, which can enable financial institutions to improve their cybersecurity, fraud detection, trading optimization, portfolio management, customer service, and natural language processing.



However, quantum computing also poses some challenges and risks that need to be addressed. These include the availability and scalability of quantum hardware, the development and validation of quantum software and algorithms, the transition and compatibility of quantum cryptography with classical cryptography, the ethical and regulatory implications of quantum computing, and the potential threats from quantum adversaries.



Financial institutions that want to leverage quantum computing should start preparing now, by assessing their current and future needs and opportunities, building their quantum capabilities and skills, collaborating with quantum experts and partners, and experimenting with quantum solutions. By doing so, they can gain a competitive edge in the quantum era.
