Software improvements keep quantum cats at bay

Potentially dead or alive in the water for now

It seems that there is life in conventional computing yet as a better-written algorithm bested Google’s Sycamore quantum computer.

In 2019, the Sycamore computer was used by Google to demonstrate how a quantum computer could complete a task that would be impossible for ordinary computers.

At the time Sycamore achieved quantum supremacy in a task that involves verifying that a sample of numbers output by a quantum circuit have a truly random distribution, which it was able to complete in 3 minutes and 20 seconds. The Google team said that even the world’s most powerful supercomputer at the time, IBM’s Summit, would take 10,000 years to achieve the same result.
