πŸ“‘ Why Google’s Quantum Supremacy Milestone Matters

Bookmarked Opinion | Why Google’s Quantum Supremacy Milestone Matters (nytimes.com)

The company says its quantum computer can complete a calculation much faster than a supercomputer. What does that mean?

With Google’s annoucement that they had achieved “quantum supremacy”, Scott Aaronson tries to explain why this is so significant. Mikhail Dyakonov still believed there are too many variables:

To my mind, quantum-computing researchers should still heed an admonition that IBM physicist Rolf Landauer made decades ago when the field heated up for the first time. He urged proponents of quantum computing to include in their publications a disclaimer along these lines: β€œThis scheme, like all other schemes for quantum computation, relies on speculative technology, does not in its current form take into account all possible sources of noise, unreliability and manufacturing error, and probably will not work.”

I must admit that my head still spins trying to make sense of the field. I still therefore think Jim Mortleman and Stuart Houghton have done the best job at trying to explain it.
