The research looked into using quantum machines to price complex derivatives, one of the most computing-intensive tasks in the financial markets and a significant cost for banks. The calculations rely on so-called Monte Carlo simulations, which involve making a large number of projections about future random market movements to calculate the probability of a particular outcome. The research pointed to near-term breakthroughs that will make it possible to quote prices over the phone to customers looking to trade complex derivatives, rather than wait the hours it can sometimes take to run calculations using today’s computers
