Sabine likes to come down on quantum computing, but always leaves something out. In this case, she ignores interconnect as the path to scale. Yes, you can only fit so many logical qubits in one "box" per modality ... but you then connect many of those boxes!…

Not cold enough for most quantum computing modalities.

Quantum computing is best done in the permanently shadowed craters on the Moon

Quantum dating app? HitoMatch claims to use quantum computing to pick matches. I don't know, I think the biggest problem in dating isn't physics ... it's chemistry.

"Compared to previous quantum supremacy demonstrations, the big advantage here is that the output is a single number rather than a sample from a distribution, and therefore is in principle, efficiently verifiable — if not using a classical computer, then at least using a second…


I'll be part of a fireside chat panel at the IQT Quantum + AI Conference today at 3:35pm here in NYC. If you're around, come say hi and ask a question. We'll be covering the quantum computing threat to blockchain, primarily.

40 years later, work in quantum tunneling wins a Nobel Prize. Clarke, Devoret and Martinis contributed to quantum computing this way, but David Deutsch was robbed IMO.
