The @zotero.org translator for Nature Communications was fixed a while ago, but the problem persisted until recently for other journals, e.g. Nature partner journals (see my post on Zotero's forum from a few months ago: forums.zotero.org/discussion/1... ). This goes deeper than I thought!

5/ Why these things matters: better targets → faster progress → more robust devices in, e.g., photonics & atomic systems.

4/ Universal precision bounds for quantum metrology with correlated noise (beyond i.i.d.) valid for general adaptive strategies https://doi.org/10.1103/jy3v-wkcb

3/ A general framework to compute the ultimate precision for measuring multiple parameters of Gaussian quantum states: https://arxiv.org/abs/2504.17873

2/ A numerical framework to understand the precision of time-continuous sensing with inefficient detectors (or other Markovian noise) https://arxiv.org/abs/2504.12399 https://doi.org/10.1103/ljh3-3l4j

My guess would be mostly out of habit. However, the fact that the second matrix is Hermitian may have some benefits (e.g. specialized numerical routines).

Participation is free of charge, but space is limited. The call for abstracts for oral or poster contributions is now open, with a submission deadline of February 1, 2025.

Simone Felicetti (@simonefelicetti.bsky.social), Roberto Di Candia, and I look forward to seeing you in Pisa!
