Remember Microsoft's announcement of the quantum computing breakthrough. Well that isn't looking great. In today's video I have a summary of the most recent developments. youtube.com/watch?v=bJTsFZ…

These four parameters seem trivial to me. What matters, and what Nature referees and editors should look into, are fusion gate success probability, single-pair system efficiency, multiplexing efficiency, and optical switch bandwidth and efficiency.

Alan Baratz Don't forget to mention these two papers that just came out: * arxiv.org/abs/2503.05693 * arxiv.org/abs/2503.08247 They both show how to simulate D-Wave's Advantage2 system classically!

Do you see a superconducting gap in this data or just a mess of disorder? This is the reality of Microsoft Quantum's devices... Their recent Nature claims a ‘parity readout’ but the conductance data (not presented) tells a very different story. Read more: arxiv.org/pdf/2503.08944

Hey whurley, it's been 3 years already! Have you finally solved transportation with quantum? If not yet, we'll check in with you in another year. x.com/whurley/status…

“The gap protocol is flawed,” said Henry Legg of the University of St Andrews. “The foundations to build a topological qubit aren’t there, and anyone claiming they have built one today is selling a dangerous fairy tale.” physics.aps.org/articles/v18/68

instead of investing billions of dollars to make quantum computers break cryptography, why don't we just get ourselves added to the national security group chat?

It’s the arrogance i find most galling. The repeated appeals to the same playbook and acting that it’s everyone else’s problem that we just don’t take them at their word (this time) and defer to their superior expertise (this time).

“The data was incredibly unconvincing. It is as if Microsoft Quantum was attempting a simultaneous Rorschach test on hundreds of people,” says physicist Henry Legg of the University of St. Andrews in Scotland sciencenews.org/article/micros…
