SUMMARY:ICFO | CHRISTOPHER W. WÄCHTLER 
CLASS:PUBLIC
DESCRIPTION:The widespread belief is that quantum systems need to be protec
 ted from the environment as well as possible for quantum technology to ful
 fill its promise of revolutionizing computing\, communication\, and sensin
 g. However\, the advent of the Noisy Intermediate-Scale Quantum (NISQ) era
  forces us to investigate dissipation and decoherence and to find ways to 
 utilize them effectively. This talk aims to provide examples where interac
 tions with the environment play a pivotal role in generating and detecting
  collective quantum phenomena\, inspiring new perspectives on harnessing e
 nvironment interactions for advancing quantum technologies. Firstly\, we w
 ill delve into the emerging field of topological quantum synchronization\,
  a novel form of synchronization where topology and dissipation intertwine
  to protect synchronized dynamics against perturbation. Next\, we will exp
 lore how carefully tailored interactions with the environment induce energ
 y migration within small quantum spin networks characterized by a superrad
 iant speed-up\, demonstrating the potential for utilizing dissipation as a
  resource rather than a hindrance. Finally\, if time permits\, I will intr
 oduce a novel methodology for probing quantum criticality in non-equilibri
 um systems. This method circumvents the shortcomings of standard perturbat
 ive expansions\, enabling a comprehensive and thermodynamically consistent
  understanding of critical phenomena in systems coupled to non-Markovian r
 eservoirs.&nbsp\;
