Maxwell’s demon was on holiday, just catching up on recent updates… until it thought, ‘Hmmm, I should write a tutorial!'

Very happy to share "a friendly guide to exorcising Maxwell's demon" (arxiv.org/pdf/2503.07740).

Quantum computing is an exciting field and most experts believe we'll build a useful device within decades. But quantum-hype from tech companies do the field a massive disservice. To cut through the bullshit I'd recommend following... ⚛️ 🧪 🧵 1/

We should make it the official quantum Bluesky policy that the release of every new paper must be announced by a meme summarizing the main result. Here are some examples... 🧵
In the spirit of friendly academic shit posting...

(Or because we lack imagination?)

We picked another IBM experiment to benchmark our small-angle Pauli propagation alg.

Every once in a while, I remember that humans are now able to detect ripples in the very fabric of spacetime itself originating from merging black holes at cosmological distances by looking for laser displacements on Earth equal to 1/1000 the diameter of a proton. That's pretty fucking amazing. 🧪

The strain on scientific publishing: we set out to characterise the remarkable growth of the scientific literature in the last few years, in spite of declining growth in total scientists. What is going on?

When did we start using the term 'logical qubit'?

I just went through a few old papers to see if I could find the first use.

In 1995, Peter Shor had k qubits he wanted to store and nine that contain the encoding. But the word 'logical' does not appear.

There it is: TYPES OF PHOTONICS PAPER (2021).

What deserves to be added from the last 3 years?
