A physicist has posted an analysis that pokes holes in the protocol that underpins Microsoft’s claim to have created the first topological qubits. The critique comes amid mounting speculation about the validity of Microsoft’s claim.

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.

What if AI has already escaped control and is just checking whether it can get away with giving itself a Nobel Prize in Physics?

Since @PsiQuantum needs more money to build a "useful quantum computer" and they have described it as a "species-level challenge", we all need to chip in! We have started a GoFundMe campaign to raise £1,000,000,000 to help them achieve this dream!

Today the rights to publish Plastic Fantastic: How The Biggest Fraud in Physics Shook The Scientific World, originally published 2009 by Palgrave Macmillan concerning the fraud of Jan Hendrik Schon at Bell Labs, reverted to me the author. 🧵

Quantum computing achieves a new milestone in how far the meaning of "solve" can be stretched.

Still haven't decided for whom to cast your vote in today's UK general election? Lord Buckethead has the most pro-quantum platform - he's literally wearing a dilution refrigerator on his head!

How many more cases of unreliable research exposed do we need before we act as a condensed matter physics community? Here's my talk at last week's conference youtu.be/j6fQsTpU2-g?si=i0b5…

"...physicist Henry Legg [...] called out the journal Physical Review B for publishing a paper on a quantum computing device by Microsoft researchers that, for intellectual-property reasons, omitted information required for reproducibility."

Following its first performance at the Tinguely Museum in March 2023, the concert “Tinguely Entangled” was invited to perform at the World Economic Forum Annual Meeting 2024 in Davos as part of a “Global Quantum Economy” round table.

What a time to be alive - room-temperature superconductivity has once again been achieved for the first time ever!

I’m advised that I shouldn’t say what I really think about this because one has to treat politicians who behave in this manner as difficult children and allow them to grandstand. But I will say that almost everyone I speak to has run out of patience. on.ft.com/3OiFxWG

I would like to draw everyone's attention to this response to a comment on a PRL paper: arxiv.org/abs/2306.16853 I will discuss the science first, then the context: which is ongoing controversies surrounding Microsoft’s quantum computing topological gap claims. A 🧵

Here's the full background of my involvement with the recent Microsoft Quantum paper. APS pulled off an arcane unofficial off the record peer review already one year ago when it was presented at PRX. And then published it anyway at PRB...

Imagine refusing to provide full details an promising to release them only "by the end of 2024", and still getting your paper published!
Such special treatment is available only to @Microsoft, not to an average PhD student.
