Summit v Sycamore

CrossRoads:
How about some context?

Summit is the presently the world's fastest conventional computer.
Sycamore is a 54 qubit quantum computer Google is working on with NASA.

A report appeared briefly on a NASA website saying that Sycamore, with only 53 qubits working, had solved in minutes a problem that it was estimated would take Summit millennia to complete.

The report disappeared.
IBM dispute what has been done.

No doubt there is still a long way to go but perhaps we will see something really big in our lifetimes?
