After trying out algorithmic trading on a quantum computer, HSBC recently joined a growing list of companies to claim that a revolutionary new form of computing was finally coming into its own. The experiment was a “world first in bond trading” that showed “we are on the cusp of a new frontier of computing in financial services”, the bank said. Some quantum experts are not so sure. Scott Aaronson, a professor of computer science at the University of Texas, dismissed it as one of an increasing number of “zombie claims” of quantum computing’s superiority. “There’s absolutely no reason to believe any improvement they saw had anything to do with quantum mechanics,” Aaronson said. Even HSBC’s own researchers wrote that they were not able to explain how the IBM machine they used had achieved the superior trading results, adding that their work “requires further investigation”.

Full report : Amid some scepticism, many say quantum computers can now achieve results beyond the capability of traditional computers.
