We will need, for instance, to vastly increase the quality of qubits to implement some of the algorithms detailed here. The go-to for providing suggestions, feedback and questions is our email address info@quantumwa.org. The speed at which significant developments occur will increase. While the problem of determining the optimal arbitrage opportunity is NP-Hard, these can be detected efficiently using quantum annealers. Downtime on infrastructures using quantum computing will be close to non-existent. Abstract. Regression algorithms are generally used to understand how the typical value of a response variable changes as an attribute is varied.

In the following, we discuss some early attempts to tackle financial problems through quantum computing. Financial data encoded with quantum cryptography is by far more secure than other kinds of digital security. Ascent: Quantum finance opportunities: security and computation [https://atos.net/wp-content/uploads/2017/02/Ascent_White-Paper_Quantum-Finance-FINAL-Nov2016-1.pdf], 2017, Open Source Strategy Forum: “Quantum Computing, Open Source and the Future of the Financial Services Industry” [https://opensourcestrategyforum.org/talks/quantum-computing-open-source-and-the-future-of-the-financial-services-industry/], 2017, Prado, Marcos Lopez de, (2016). Faster processing is made possible because, in quantum computing, data gets represented using qubits as opposed to traditional binary units (0s and 1s). Risk management, an area that has grown massively in importance to financial institutions over the last decade, could also experience a major upgrade through the use of quantum computing. The implications of quantum computing will be far-reaching. Until then, quantum computers are a significant threat to existing infrastructures, including blockchain, according to Technology Review (2017). Due to the growing number of derivative products, only Monte Carlo simulations are viable, but at a huge computational cost and lengthy execution times. Financial derivatives contracts have a payoff that depends on the future price trajectory of some asset (which can have a stochastic nature). Quantum Hidden Markov models may deliver better and faster forecasting. They can either charge a fee for the risk of granting the loan — the higher the risk, the higher the interest rate — or cope with the risk statistically, by diversifying their loans, and trying to compensate their losses by relatively large gains. Quantum technology’s ability to handle billions of transactions per second will be a welcome addition to banking institutions which are overloaded continuously with vast volumes of transactions. Functions such as the approval of bank loans and mortgages will be more automated moving forward. Another possibility altogether is to design new, fully quantum neural network algorithms able to learn much more complex data patterns than those identifiable using a classical neural network. There are some lines of activity in this field: - In an early implementation a D-Wave quantum computer has been used in a Proof-of-Concept to train a specific type of neural network (a Boltzmann Machine. These concepts are of importance in portfolio optimization. While forecasting from already trained machine learning algorithms is usually extremely efficient, the training itself can be computationally expensive. In addition to data processing, fraud detection is also a relevant use-case when it comes to quantum banking. This solution could be the most hack-proof development of the Internet of Things (IoT) era. Finance can be defined as the science of money management, a discipline almost as old as civilization itself. This is crucial when some of the data might be irrelevant or weakly correlated to the output, when we do not have access to all the data, or when using all the data is too computationally expensive. In finance, the stochastic approach is typically used to simulate the effect of uncertainties affecting the financial object in question, which could be a stock, a portfolio, or an option. The financial sector has many transactions run by algorithms. Where it really shines is in dealing with extremely large or complex systems, which cannot be approached analytically or handled through other methods. The classical approach to this problem is via simplified scenarios, such as the Black-Scholes-Merton model, and Monte Carlo sampling. The potential benefits of quantum computing in finance. The way this problem is typically dealt with relies on a machine learning method known as classification. Optimal arbitrage opportunities: the concept of arbitrage is the idea of making profit from differing prices of the same asset in different markets, while bearing no risk. To learn more.

Quantum annealing, on the other hand, naturally provides methods to identify better solutions for this type of problems. The finance sector has advanced over the past decade with developments in computer processing and smartphone technology. This is the case for stock market simulations, for instance, which are routinely day-long simulations. In 1776, Adam Smith, the Father of Capitalism wrote: “No society can surely be flourishing and happy, of which the far greater part of the members are poor and miserable.”, ✪ Integrity ✪ Curiosity ✪ Serendipity ✪ Humanity ✪ Prosperity, Future Use-Cases of Quantum Technology in Financial Services. This is an NP-Hard problem, meaning it is extremely difficult — if not impossible — for classical computers to solve efficiently. Human interaction will only be relied upon to ratify flagged-up solutions. The problem with Monte Carlo methods is that, if we want to obtain the most probable outcome of a wide distribution or obtain a result with a very small associated error, the required number of simulations can become gigantic.
