This week We had two nice seminars: Teruaki Nagasawa (Nagoya U) discussed Macroscopic states and operations: a generalized resource theory of coherence.
Ricard Puig (EPFL) examined Barren plateaus & warm starts, shedding light on quantum loss landscapes and effective training strategies for VQA.

New paper on arXiv🔥
How can many-body interactions boost quantum sensing to its limits?
We show how to add controlled interactions in many-body probes to reach the highest precision limits in quantum metrology -- both for dynamical and steady states.

From the people who tend to look down on "curiosity-driven" research, sure enough we get a bit of money-driven research. In that world, given that google evidently hasn't got the brain power to solve the problem, it's only rational to farm it out.
