re: Google Acheives Quantum Supremacy

Sounds like a gimmick.

We’re still years to decades away from a QC powerful enough to implement Shor’s algorithm for breaking RSA encryption. Someone demonstrating error correction and logical qubits will be a much bigger deal than what Google showed recently. Still a neat result.

And thats under the assumption they would be willing to make this information known to the public.

The Wizard of Oz is really a supercomputer. One day they will rule humanity. Millions of cameras will track your movements predicting your next move, and intervening.

The best way QC was explained to me is this way. Imagine a 10 story building with 10 rooms on each floor. The task is to find which of the 100 rooms this person is hidden in. Modern computers would achieve this task by looking in each room one at a time until it found the right room. A QC would look through all 100 rooms at the same time.
