Unfortunately, today’s quantum computers either can’t run those algorithms or can only run simplified versions that classical computers can also handle. This has left the field facing a challenging question: Can we demonstrate the promise of quantum computers on today’s noisy, limited hardware? And given that today’s quantum computers are somewhat error-prone, getting the wrong result is a distinct possibility. On Thursday, the company announced three new entries that it says clearly show a quantum advantage, each using a different approach to overcoming errors and validating quantum results. Trust, but verifyAt this point, there have been many claims of quantum advantage, and at least one has the potential to be useful.
