It was defined and discussed in arxiv.org/abs/quant-ph.... It's also the Choi state of a channel that is PPT and antidegradable, but not entanglement-breaking.

A PPT-entangled and 2-extendible 2-qutrit state | Felix Leditzky
Post describing a PPT-entangled, 2-extendible 2-qutrit state, showing that the intersection of PPT and 2-extendible (or equivalently, antidegradable) states strictly contains the set of separable stat...

Today, among the 128 quant-ph new submissions, at number 97 you'll find this one. I think we've now earned the right to call it "the Bayes-Petz rule".

Inevitability of the Petz transpose map
Bayes' rule is central to classical statistical inference: given a prior and a stochastic model, it determines the corresponding retrodictive conditional probabilities. In quantum theory, however, the...

Researchers estimate RSA-2048 could be broken with 22,593 cat qubits in 3.14 days, assuming idealized hardware with no bit-flips (about 45,000 under more realistic assumptions). It's a theoretical estimate, not a demonstration.
