Quantum computing has the potential to dramatically affect banking in the coming years, especially from a cybersecurity standpoint; banks like JPMorgan Chase, Barclays and Morgan Stanley have all started sinking capital into applications in hopes of trying to stay ahead of the next wave of innovation; quantum computing allows for the breakdown of large sets of data significantly faster than classical computing; this puts banks at risk if an attack were to happen and also gives them power is they were to develop an application; as AI and blockchain begin reaching certain levels of acceptance, quantum computing looks to be the next stage of innovation in finance.
