Pseudo Twirling Mitigation of Coherent Errors in non-Clifford Gates
Jader P. Santos, Ben Bar, Raam Uzdin
The conventional circuit paradigm, utilizing a limited number of gates to construct arbitrary quantum circuits, is hindered by significant noise overhead. For instance, the standar…
Joint fluctuation theorems for sequential heat exchange
Jader P. Santos, André M. Timpanaro, Gabriel T. Landi
We study the statistics of heat exchange of a quantum system that collides sequentially with an arbitrary number of ancillas. This can describe, for instance, an accelerated partic…
Landauer's principle at zero temperature
Andre M. Timpanaro, Jader P. Santos, Gabriel T. Landi
Landauer's bound relates changes in the entropy of a system with the inevitable dissipation of heat to the environment. The bound, however, becomes trivial in the limit of zero tem…
Collisional quantum thermometry
Stella Seah, Stefan Nimmrichter, Daniel Grimmer +3
We introduce a general framework for thermometry based on collisional models, where ancillas probe the temperature of the environment through an intermediary system. This allows fo…
Wigner entropy production and heat transport in linear quantum lattices
William T. B. Malouf, Jader P. Santos, Luis A. Correa +2
When a quantum system is coupled to several heat baths at different temperatures, it eventually reaches a non-equilibrium steady state featuring stationary internal heat currents.…
Spin-phase-space-entropy production
Jader P. Santos, Lucas C. Céleri, Frederico Brito +2
Quantifying the degree of irreversibility of an open system dynamics represents a problem of both fundamental and applied relevance. Even though a well-known framework exists for t…
