White Paper The case for quantum and quantum-inspired computing in financial services

When mathematical calculations get complex enough, they hit the limits of current computing, especially when it comes to optimization calculations. Here, the number of options to be tested in search of the best possible combination can quickly result in numbers that stretch out towards infinity. Until recently, these calculations could be so time-consuming that, by the time an answer was found, it was no longer relevant.

The complexities are mind blogging: in the case of traditional Data Encryption Standard (DES), today’s fastest supercomputer would take around 21 billion years – or one and a half times the age of the universe, to calculate the correct prime factors of a number with 617 decimal digits (in other words, a 2,048-bit key. However, with a quantum computer, this task could be manageable instantly.
