DESCRIPTION:Speaker: Robert Ott\nhosted by Maximilian Prüfer\nAbstract: Ab
 stract :In this talk\, I discuss the role of quantum error correction in e
 nhancing quantum sensors. I will begin by reviewing established results on
  how and when quantum error correction protocols can be used to protect se
 nsors in noisy environments. Then\, I will present our recent work\, where
  we developed a protocol to detect rare stochastic signals in a noisy envi
 ronment using quantum error correction. Specifically\, I will show how we 
 achieve an improved sensitivity of our approach over more conventional sen
 sing strategies.[This talk is based on arXiv:2601.04313.]

DESCRIPTION:Speaker: Jie Ren\nhosted by Maksym Serbyn\nAbstract: Abstract: 
 Understanding how complex systems transition between order and chaos is a 
 central challenge of nonequilibrium physics. While weak perturbations of c
 lassical integrable systems give rise to a mixed phase space of coexisting
  regular and chaotic trajectories\, analogous behavior in interacting quan
 tum many-body systems has remained elusive. Here we develop and experiment
 ally implement a hybrid quantum–classical feedback protocol that autonom
 ously discovers and stabilizes long-lived regular trajectories in a superc
 onducting quantum processor. Each iteration combines short-time quantum ev
 olution with classical optimization that projects the dynamics back onto a
  low-entanglement variational manifold\, effectively distilling coherence 
 from chaotic evolution. The stabilized trajectories reveal a quantum many-
 body mixed phase space emerging from nonlinear variational dynamics\, with
 out a direct analogue in classical or few-body quantum systems. Our result
 s establish a versatile framework for algorithmic discovery and control of
  coherent dynamics previously inaccessible to experiment.
