(Phys.org) A major new change in fintech is now in sight through the possible implementation of quantum computers. Instead of binary bits—the classic elementary unit of information—quantum computing uses qubits (quantum bits), obtained by the superposition of binary states. This would allow them to process a much larger amount of information thousands of times faster than classical computers.
Amid such hope, caution is necessary: financial and economic data are truly complex, and analysis will not necessarily lead to more accurate predictions given the complexity of data. The complexity and non-stationarity of data might defy analysis. The global effect of quantum computing on economic and social life will depend on the use that will be made of this tool—and that stems from human decisions rather than being forced by knowledge itself.
