Optical computer beats quantum tech in tricky settlement task
Microsoft’s analog technology twice as accurate compared to IBM’s quantum kit in Barclays experiment

Barclays has entered a joint development agreement with Microsoft to explore an application for an optical computer that has already outperformed a quantum computer by two orders of magnitude.
In April, Microsoft released a paper detailing how it used its optical computer called Aim to solve optimisation problems including one focused on transaction settlement that had been tackled in a 2019 Barclays-IBM quantum computing collaboration.
