Honeywell says it built the world's most powerful quantum computer
When it comes to quantum computers, we tend to think of companies like Google and IBM as the big players in the field, but there could soon be more competition in the space. Honeywell says sometime in the next three months it will unveil a quantum computer that is at least twice as powerful as any current device.
Breaking down that claim requires some context. As Protocol points out, most companies talk about qubits when they speak to the capabilities of their machines. For instance, Sycamore, the computer Google claimed last year achieved quantum supremacy, had 53 qubits. Honeywell is instead using a metric called quantum volume to talk up the capabilities of its machine. IBM coined the term, and here's how it defines it:...
