I agree that many in the financial sector do not know much about quantum computing, but it also does not seem that some in the quantum that do not understand the details of the problems that the financial sector has either.
For instance, those in the capital markets/trading floors in Europe and North America do significant risk calculations with hundreds or a thousand variables on up to 100,000 positions with a certain confidence. Many of these risk calculations need to be reported nightly to regulators. These financial companies are paying many millions per year to AWS, Azure, or Google to do these calculations on classical computers.
However, many parts of these calculations could be done with quantum computers relatively instantly, given enough qubits. I realize that the technology and reliability is not there today, but hopefully it will come soon.
I would not be surprised if by 2035 using quantum computers to do many variable risk calculations would become (almost) mandatory for major European and North American financial companies.
What makes you say this? Which particular quantum algorithm do you think gives an exponential speedup for multi-variate risk predictions? And why do you think there is any chance in hell that a quantum computer would exist by 2035 that could even store an input of the size you're talking about, nevermind have spare qubits to actually process it?
