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:
So, with this morning's @NobelPrize awarded in part to Giorgio Parisi for his work on complex and disordered systems, now might be a good time for a Twitter thread to explain just what exactly a spin glass is, since I've spent a lot of my career working on quantum glasses. 🤔

This is a result of Hurwitz’s theorem, one of the greatest theorems of all time, arguably an inflection point in human evolution, which tells us that the only real normed division algebras are the reals, complex numbers, quaternions, and octonions. It’s lowkey been a dream of…
What’s the cleanest and simplest explanation for why 2D (complex numbers) and 4D (quaternions) numbers exist, but not 3D numbers?
Both Ezra and Ben are wrong here, scaling laws are *power laws* which are neither exponential nor logarithmic in resources. It's like y = ax^b for constants (a, b). This slows down exponential hardware progress / investment but it's still exponential.
wait this is very stupid. the relationship is like, the opposite of exponential? the scaling laws (as i understand them) seem to indicate for each bump in capabilities has an exponential increase in cost, which is why each training run uses 10x more FLOPs than the last.
This looks very good: x.com/pesimeon/statu…
@michael_nielsen Weisskopf did the first calculation that I’m aware of. It’s a classic calculation in “back-of-the-envelope physics,” and you can use it to estimate Olympus Mons and the minimum size of spherical asteroids (~400 km, IIRC). astro.princeton.edu/~burrows/class…
Enjoyed this: x.com/fgrosshans/sta…
@michael_nielsen 2/n Not exactly the computation I remember from my first quantum mechanics course, but a simple version of the argument an be found here mit.edu/~azlokapa/ques… The idea is too high mountains have their bases melting under pressure, which we can compute by setting mGh=E,
Curious what sets the scale of the height of the highest mountains. What’s the deepest explanation for why it’s ~10km on Earth, not 1 or 100 etc. Can it be deduced from radius and density and not much else? Does it then work for the moon, Mars and so on?
@michael_nielsen There is a well known order of magnitude calculation which relates the size of the mountains, the radius of the planet, and a bunch of fundamental constants (h, c, G). It gives reasonable numbers for Earth, as well as maximal radius of dwarf planets (I'm looking for it)
@michael_nielsen 2/n Not exactly the computation I remember from my first quantum mechanics course, but a simple version of the argument an be found here mit.edu/~azlokapa/ques… The idea is too high mountains have their bases melting under pressure, which we can compute by setting mGh=E,
@michael_nielsen 3/n m is the mass of a single 'rock molecule' and E the energy to make it melt (.1 eV), which can be deduced from QM. h is the max height of a mountain, an g the local gravity It gives h=E/mg. Since g= 4πGrρ/3, you can see that hρ is constant among planets of same composition
@michael_nielsen 4/4 And bodies of radius below √hρ have no reason to be spherical, and look like asteroids. Taking the number from Earth, in km, it corresponds to √8×6400 = √51200 = 160√2 ≈ 200 km, which seems to be in the correct ballpark for small round asteroid diameter
@tahantech How else are we supposed to design such phenomenal low-pass filters? I mean, look at that suppression in the stop-band! No re-entrance in sight!
Q: Can we see highly complex entanglement from a few single-qubit measurements? I always assumed this is impossible as entanglement can be too nonlocal for local measurements to see In arxiv.org/abs/2404.07281, we prove that it can actually be done for almost all quantum states
@Quantum_Kishor @imagAndrewGuo @MSoleimanifar @preskill Many PRSs do permit an efficient query oracle, e.g., random binary phase states. The main difference is in the task: > PRS considers distinguishing an unknown state from Haar random states. > Certification considers distinguishing an unknown state from a known target state Ψ.
@RobertHuangHY @imagAndrewGuo @MSoleimanifar @preskill Ah I see. Beautiful!
This is HUGE!!! In response to our challenge, IBM's "quantum utility" experiment has been simulated on Commodore 64! A breakthrough demonstration of Quantum Disadvantage!
Can a quantum computer beat a ... Commodore 64?
check out our new results: Hamiltonian Simulation in the Interaction Picture Using the Magnus Expansion arxiv.org/abs/2404.02966 with @congminhc1 @IBM @IBMResearch
Based on what they’re saying (and not saying) here, my guess is that this is less than meets the eye. But a technical description of what was done could clear up any doubts.
A joint Quantinuum and @Microsoft team has demonstrated logical qubits so reliable they reduced circuit error rates by 800x and operated clearly below break-even. Read more in the blog post: quantinuum.com/news/a-new-bre…
There’s an technical document that might be posted as a preprint after they get their media splash. Based on a quick look, the 800x number comes from post selection but much more modest real gains with only error correction.
I don’t see an improved two qubit gate compared to bare physical error rate. Seems like a promising incremental contribution.
@quantum_graeme Yes, but to my taste, we need fewer “phases”. The NISQ era was a bit overhyped before and is a bit underhyped now. I think good research questions should speak for themselves.
Honestly happy for Microsoft, who have apparently moved on from their “pretending to have qubits” phase into their “using someone else’s qubits” phase.
