I set up an account on blue sky now and will be actively posting there. It seems most of the q. info. community has left twitter for the moment. I'll still log on to twitter to check and see what people are posting here, but I won't post anything here for now

Machina Ex Quanta: Rise of the Quantum Boltzmann Machines

Boltzmann machines are a well established model for classical machine learning, based on ideas rooted in physics like thermal distributions. Roughly eight years ago now, quantum Boltzmann machines...

Joint work "Evolved Quantum Boltzmann Machines" w/ Michele Minervini & Dhrumil Patel now online: arxiv.org/abs/2501.03367 Our paper has 3 main contributions: (see below) 1/n

Evolved Quantum Boltzmann Machines

We introduce evolved quantum Boltzmann machines as a variational ansatz for quantum optimization and learning tasks. Given two parameterized Hamiltonians $G(θ)$ and $H(ϕ)$, an evolved...

As a bonus, we prove that for general parameterized families of states the Fisher-Bures and Wigner-Yanase information matrices differ by no more than a factor of two in the matrix Loewner order, and we discuss applications in metric-aware gradient descent and estimation tasks

we also thank those who wrote helpful reviews on quantum generalizations of Fisher info, without which we would not have been able to make the progress reported in this paper, arxiv.org/abs/2410.24058, & arxiv.org/abs/2411.18268. This includes @sidhu_jasminder @jj_xyz @FarisSbahi

Joint work with Vishal Singh and @TheshNura now available on the arXiv: arxiv.org/abs/2412.18556 We define the notion of extendible quantum measurements and use it to establish limitations on classical communication over quantum channels.

Journal of Mathematical Physics now has an ad on the bottom of their website, which says "click here to view PDF". Usually I am aware of spam, but this really did look like something to click on to download the paper. After doing so, spam software was downloaded to my computer.

Journal of Mathematical Physics and @AIP_HQ , how did we reach this point? This is really disappointing. To be precise, I was trying to download the following paper when this happened: pubs.aip.org/aip/jmp/article…

Wigner–Yanase information on quantum state space: The geometric approach

In the search of appropriate Riemannian metrics on quantum state space, the concept of statistical monotonicity, or contraction under coarse graining, has been

QIS question: There have been many breakthrough algorithms for thermal state preparation recently. Does anyone know whether any of them prepare a canonical purification of a thermal state? i.e, the following state (\sqrt{e^{-H}/Z} ⊗ I) ∑_i |i⟩ ⊗ |i⟩ 1/2

The short answer to my question is "yes" and it is easily checked by reading various papers and doing some simple calculations. Thanks everyone for your replies.
