@xinwhyi Well I guess lots of people have moved off X (for obvious reasons), but there isn’t really a consensus on the best alternative. Early options like mastodon never managed to clear the field; I think people like bluesky because it resembles early Twitter (e.g algorithmic feed)

@xinwhyi they might have all moved to https://t.co/lwmnZOVDAT :)

"Can anyone explain why Gautam didn't attend the faculty meeting yesterday? I know he's traveling and it's in the middle of the night there but the meeting was virtual. All he needed was an Internet connection. Technical difficulties?"

@Quasilocal @ktibus So does this mean 41% of Australians have been to 11 or more countries??

Wake up in the morning feeling like P = NP;
Grab my tea, I'm out the door like the polynomial hierarchy.
Before I leave, brush my teeth with a tube of St. Ives
Because this evening, I'm accepting my Millennium Prize.

@VictorGalitski @DulwichQuantum Indeed, just as political incentives can lead to "Newspeak," business incentives can lead to "NewScience" (and scientists)

@JohriSonika @DulwichQuantum If your business model is solely based on getting people to prefer quantum computers when there's no differential between them and classical compute power, there's no way your company's worth a billion $

[Andrew Guo @imagAndrewGuo]

@JohriSonika @DulwichQuantum I think the context is clear from the paragraph above it in the article? 'Christopher Monroe [...] says that claims of quantum supremacy are “over the top” and that quantum computers could become valuable tools even if their abilities can still be matched by classical machines'

@Quantum_Kishor @RobertHuangHY @MSoleimanifar @preskill I think the procedure assumes that you have access to an oracle that, given a bit string x, returns the corresponding amplitude of the target state |psi>, <x|psi>. So the claim is that you can certify the state using few samples with an oracle that may not be efficient to produce

I’m proud to announce the April 1 launch of my new startup, Open Asteroid Impact! We redirect asteroids towards Earth for the benefit of humanity. Our mission is to have as high an impact as possible. 🚀☄️🌎💸💸💸

Chapters 1-11 now out! https://t.co/At7uLMa2yN

[Anthony Leverrier @letonyo]

Wow, the latest draft of Daniel Gottesman's book on quantum error correction is available!
A must-read for anyone interested in this field:

[Michael Nielsen @michael_nielsen]

One of my favourite letters, insightful & humane, from Richard Feynman to a former student who was having a rough time

I was reflecting on it as an argument in favour of scope insensitivity, or even in favour of smaller problems:

@CraigGroves6 @PicturesFoIder But Heisenberg was playing for the other side!

@lmaogh (In case anybody asks, no, you can’t break RSA using NISQ-era devices: https://t.co/z10LDz7VXZ)

[Andrew Guo @imagAndrewGuo]

@lmaogh But hey, look at this one paper that factors 48-bit numbers using 10 qubits and claims they can break RSA-2048 using 372: https://t.co/T5WqeVf5wV Is this the future? Hide yo credit cards and cryptocoins, everybody—Schnorr’s algorithm is coming for you

@MStoudenmire The obstacle with converting most circuit decompositions of the QFT to Hamiltonian evolution seems to be the H gates, which are cleverly avoided by the construction of Q^P_n in section II.C

[Andrew Guo @imagAndrewGuo]

@MStoudenmire Really cool work! One question that's been on my mind for a while (ever since https://t.co/yPy6z7BfRh) is whether there's a way to explicitly implement the bit-reversed QFT by evolving a Hamiltonian with exponentially decaying interactions for constant time

@zlatko_minev Nice write-up on this paper (and related work) by Jennifer Oullette here: https://t.co/t4aYWHtXDj

@postquantum Marginally less absurdist than this article, "On classical and quantum error-correction in ciliate mate selection" https://t.co/Hm2HrcJ3y6
