29.1 Application of quantum computers in the financial industry

Quantum computing has the potential to revolutionize the financial industry because it can solve complex problems that traditional computers cannot. Here are some potential applications of quantum computing in the financial industry:

• Risk management: Quantum computing can be used to simulate complex financial markets, which can help financial institutions better manage risks. For example, quantum computing can be used to estimate financial derivative prices, identify market risks and develop new risk management tools.

• Investment decisions: Quantum computing can help financial institutions make smarter investment decisions. For example, quantum computing can be used to analyze large amounts of data, identify investment opportunities and reduce investment risks.

• Financial Fraud: Quantum computing can be used to identify financial fraud. For example, quantum computing can be used to analyze financial transaction data, identify suspicious activity and prevent fraud.

• Fintech: Quantum computing can be used to develop new fintech products and services. For example, quantum computing can be used to develop new payment systems, financial trading platforms, and financial analysis tools.

Please refer to some introductory related papers published by some scholars:

• “Quantum Finance: a tutorial on quantum computing applied to the financial market“, the author introduces the basics of quantum computing and discusses how a quantum algorithm called QAOA can be applied to Portfolio optimization problem.

• "A Survey of Quantum Computing for Finance", the author comprehensively summarizes the latest technologies of quantum computing for financial applications, such as derivatives pricing, risk modeling, natural language processing and fraud detection.

• "Quantum Bohmian Inspired Potential to Model Non-Gaussian Events and the Application in Financial Markets" by Reza Hosseini, Samin Tajik, Zahra Koohi Lai, Tayeb Jamali, Emmanuel Haven, G. Reza Jafari, published in 2022. This paper is mainly based on Born mechanics to study time series containing strongly coupled events. They first proposed that their target time series appeared to be associated with more rare events than normal density, and that Gaussian statistics severely underestimated the frequency of these events. Therefore, they suggest that imposing Gaussian densities on natural processes will seriously ignore the presence of extreme events in many cases.

• “Quantum computing” by Roman Rietsche, Christian Dremel, Samuel Bosch, Léa Steinacker, Miriam Meckel & Jan-Marco Leimeister, published in 2022. This paper gives a brief overview of the three layers of quantum computers: hardware, system software and application layer. In addition, they introduce potential application areas of quantum computing and possible research directions in the field of information systems.

• “Quantum Computing and the Financial System: Spooky Action at a Distance?”, published in 2021. This article points out that quantum computers can revolutionize industries and fields that require large amounts of computing power, including simulating financial markets, designing new effective drugs and vaccines, empowering artificial intelligence, and creating new secure communication methods (quantum internet).

Currently, there are no ready-made examples of quantum computing in the financial industry. However, some financial institutions have begun to invest in quantum computing and are collaborating with quantum computing companies to develop quantum financial applications.

Here are some examples of practical applications of quantum computing in the financial industry:

• In 2021, Goldman Sachs and QC Ware collaborated to develop a quantum algorithm that can be used to simulate complex financial markets. The algorithm can be used to simulate complex financial markets. Their findings have been published in a new research paper, "[2109.09685] Low depth amplitude estimation on a trapped ion quantum computer (arxiv.org) ", which shows that IonQ's quantum computer is now powerful enough to demonstrate that Goldman Sachs and QC Ware's latest quantum algorithm, which promises to speed up Monte Carlo simulations. These simulations are critical to problem solving in many industries, including finance, telecommunications, robotics, climate science, and drug discovery. The quantum algorithms they are designing are intended to allow companies to assess risk and simulate the prices of various financial instruments much faster than today, and if successful, could change the way global financial markets work. The experiment was conducted on IonQ's latest generation quantum processing unit (QPU), which delivers an order of magnitude improvement in fidelity and throughput over previous versions. This makes it possible to run deeper circuits and many shots in a much shorter time than was previously possible.

• In 2022, HPCWire reported that (1) Nasdaq and quantum computing company Rigetti Computing cooperated to develop secure communication, fraud detection, order matching, optimization functions and risk assessment applications based on quantum key distribution technology. The collaboration will leverage Rigetti's new Aspen-M multi-chip processor and focus on "leveraging Nasdaq market perspective, domain expertise and data for machine learning, optimization and simulation problems." (2) JPMorgan Chase, Toshiba and Ciena demonstrated the full feasibility of the first quantum key distribution (QKD) network suitable for metropolitan areas, which is resistant to quantum computing attacks and can support 800 Gbps data rates , real-world environmental conditions for mission-critical applications. See their paper "[2202.07764] Paving the Way towards 800 Gbps Quantum-Secured Optical Channel Deployment in Mission-Critical Environments (arxiv.org)" for details.

• In 2023, researchers from China’s Shanghai University and Spain’s University of the Basque Country UPV/EHU will collaborate to develop quantum financial applications using the quantum computer D-Wave. Their findings have been published in a new research paper, "Toward Prediction of Financial Crashes with a D-Wave Quantum Annealer," which shows that D-Wave's quantum computers are now powerful enough to demonstrate performance on D-Wave. The latest quantum algorithm, which can predict the NP-hard problem of financial collapse in complex financial networks. In the past, there were no known algorithms that could efficiently find optimal solutions. So researchers are exploring new ways to solve this problem by experimenting with D-Wave quantum annealers, benchmarking their performance to achieve financial balance. Specifically, the conditions for balancing nonlinear financial models are embedded in a higher-order unconstrained binary optimization (HUBO) problem, which is then converted into a spin 1/2 Hamiltonian for up to two qubit interactions. The problem therefore amounts to finding the interacting ground state spin Hamiltonian, which can be approximated using a quantum annealer. The size of the simulation is mainly limited by the necessity that a large number of physical qubits of logical qubits must have the correct connections. The researchers' experiment paves the way for this quantitative encoding of macroeconomic problems in quantum annealers.

These are early applications of quantum computing in the financial industry. As quantum computing technology continues to develop, we can expect to see more quantum financial applications emerge.

29.2 Investment psychological consultant

Investment advisory firms can use market psychology technology to make recommendations to clients. These psychological technologies are based on the Darwinian psychological model of quantum intelligence.

Quantum psychological models can help us better understand the psychology of investors and the stock market crowd, thereby making more accurate predictions.

Traditional AI algorithms are typically trained using historical data and use this data to identify potential patterns in the market. However, these patterns may change over time, and therefore, AI algorithms may not be able to accurately predict future market directions.

Quantum psychological models can help us better understand how markets work and identify potential nonlinear patterns in markets. These patterns may be more difficult to identify with traditional artificial intelligence algorithms.

Additionally, quantum psychological models can help us better understand uncertainty in markets. The market is a complex system affected by many factors. Quantum psychological models can help us better understand the interaction between these factors and estimate market uncertainty.

Therefore, quantum psychological models have the potential to predict the performance of financial markets more accurately than artificial intelligence combined with Lo's evolutionary algorithms.

Here are some specific examples:

• Quantum psychological models can help us better understand investor fear and greed. These sentiments can have a significant impact on the market.

• Quantum psychological models can help us better understand the behavior of the stock market crowd. These actions can have a significant impact on the direction of the market.

• Quantum psychological models can help us better understand uncertainty in markets. This can help us make more informed investment decisions.

Of course, quantum psychological models are still in their early stages of development. We need more research and development before we can apply it to financial markets.

29.3 Quantization of evolutionary algorithms

Andrew Lo's Evolutionary Algorithm is a GA. The evolutionary algorithm he proposed is mainly used for prediction of financial markets.

Lo published a paper in 2015 proposing a financial market prediction model based on evolutionary algorithms. The model uses processes such as genetics, mutation, and selection to find the optimal portfolio.

Lo's evolutionary algorithms have had some success in financial market forecasting. For example, in 2015, Lo’s evolutionary algorithm predicted a decline in the Chinese stock market.

However, Lo has yet to publish on the application of quantum GA in finance. This may be due to the fact that quantum computing technology is still in its early stages and is difficult to be widely used in the financial field. However, Lo proposed his new paradigm of adaptive markets in his book Adaptive Markets: Financial Evolution at the Speed ​​of Thought, explaining how financial evolution is shaped by the speed of thought. behavior and markets. He also discusses the impact of quantum computing on the future of finance. With the development of quantum computing technology, Lo's evolutionary algorithm is likely to be applied to quantum GA, thereby improving the accuracy of financial market predictions. Quantum GA has great potential in finance.
