Determining stationary-state quantum properties directly from system-environment interactions
Prof. Dr. Fernando Antonio Nazareth Nicacio
Universidade Federal do Rio de Janeiro, RJ
Considering stationary states of continuous-variable systems undergoing an open dynamics, we unveil the connection between properties and symmetries of the latter and the dynamical parameters. In particular, we explore the relation between the Lyapunov equation for dynamical systems and the steady-state solutions of a time-independent Lindblad master equation for bosonic modes. Exploiting bona fide relations that characterize some genuine quantum properties (entanglement, classicality, and steerability), we obtain conditions on the dynamical parameters for which the system is driven to a steady state possessing such properties. We also develop a method to capture the symmetries of a steady state based on symmetries of the Lyapunov equation. All the results and examples can be useful for steady-state engineering processes.

Thank you everyone that participated on the SPIN off QuBIT September meeting st IFUSP!
The next meeting will take place December 06 and 07 @ Unicamp. More details to be provided soon.
Hi everyone. The SPIN off QuBIT September meeting at IFUSP will take place on the 27th and 28th, next week. A tentative schedule is now available at the event’s page.
Jens Einsert just published a call for PhD and post- doc positions in the fields of Quantum information and Quantum thermodynamics.

Hoje foi publicado na Folha de São Paulo um belo texto do Fernando de Melo (CBPF), descrevendo a gênese da mecânica quântica como exemplo da importância do debate baseado em fatos, em contraposição à era atual dos “fake news” e pós-verdade. Confiram aqui!

The Institute of Physics, University of São Paulo is inviting applications for a permanent faculty position in the field of Quantum Information. This includes quantum computation, quantum communication, quantum metrology, and their correspondent physical implementations, as well as the possible relations of Quantum Information Science with fundamental physics through areas such as holography and topological materials. The Physics Institute intends to boost its presence in Quantum Information Science and this position is a first step in that direction. The applications are open until September 24.
For more information contact Gabriel T. Landi at firstname.lastname@example.org or Gustavo Burdman at email@example.com
The University of Sao Paulo (USP) is among the top research institutions in Latin America, and the Physics Institute is a dynamic, multi-disciplinary environment.
Candidates are expected to carry out high-level, independent research, to mentor students, teach at the undergraduate and/or graduate level, and to participate in outreach activities.
Compensation is commensurate with research institutions around the world, with a teaching load similar to U.S. and European universities.
