Quantum Supremacy

Definition

The demonstration that a quantum computer can solve a problem that is practically infeasible for classical computers. Google claimed this in 2019 with their Sycamore processor.

AI Explanation

Examples

  • • Google's Sycamore completed a sampling task in 200 seconds that would take classical supercomputers ~10,000 years.
  • • IBM disputed Google's claim, suggesting classical methods could do it in days, not years.
