performance improvement in predicting bond trade fill probability over classical methods
TECHNOLOGY STRATEGY
uantum computing has been the technology of tomorrow for decades. Researchers have built increasingly sophisticated quantum processors, published thousands of papers on quantum algorithms and secured billions in funding from governments and venture capitalists. Yet the question has persisted: when will quantum computers be able to perform a task that classical computers cannot?
IBM and HSBC appear to have answered that question, with IBM quantum processors achieving what they describe as the first documented performance advantage over classical computers in a commercial application. Working with HSBC, IBM delivered 34 % better algorithmic accuracy using quantum methods compared with conventional computing approaches on problems involving multiple interconnected variables.
