Understanding environmentally-induced quantum dissipative dynamics is crucial to modeling real-world implementations of quantum systems, including materials, sensors, emulators, and computers. However, the study of universal aspects of complex quantum dynamics in systems interacting with their environments remained largely unexplored until recently. In this talk, I will report novel results on three aspects of dissipative quantum systems: (i) Signatures of Dissipative Quantum Chaos; (ii) Fidelity decay in Quantum Circuits; (iii) Observation of spectral transitions in NISQ Processors.

Pedro Ribeiro is an Associate Professor of Physics at Instituto Superior Técnico (IST) and a researcher at the Center for Physics and Engineering of Advanced Materials (CeFEMA), affiliated with the Laboratory of Physics for Materials and Emerging Technologies (LaPMET). Additionally, he is an associate member of the Beijing Computational Science Research Center (CSRC). Currently, he leads the q.m@t team at IST and is a founding member and coordinator of the QM@PT research network.His research interests lie at the intersection of condensed matter physics and quantum information, with a focus on many-body strong-correlation effects and non-equilibrium processes in open quantum systems. Prior to his current appointment, he held a Researcher and Invited Professor position at the Physics Department of IST-ULisbon (2014-2019). Before that, he was a research fellow at RQC Moscow (2014-2015). He held postdoctoral positions at prestigious institutions such as CMT-MIT, Cambridge, USA (2009-2010), CFIF, IST-ULisbon (2010-2011), and MPI-PKS, Dresden (2011-2013). He earned his PhD in 2008 from Paris VI.
