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

Further thoughts on the GPT situation in the form of an apocalyptic AI punk song. Based on "Against the 70s" by Mike Watt.

Title: Against the GPTs

The kids of today should defend themselves against GPT
The kids of today should defend themselves against GPT
The kids of today should defend themselves against GPT

Evolved (進化した？) 量子ボルツマンマシンの提案。パラメータ化された2つのハミルトニアンG, Hに対し、Gの熱状態を準備、次にHを用いユニタリ時間発展を行うというもの。これの基底状態エネルギー推定や生成モデリングへの応用を示した。

Our paper has 3 main contributions:

(see below) 1/n

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:
