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…
Scalable evaluation of incoherent infidelity in quantum devices
Jader P. Santos, Ivan Henao, Raam Uzdin
Quantum processors can already execute tasks beyond the reach of classical simulation, albeit for artificial problems. At this point, it is essential to design error metrics that t…
Adaptive quantum error mitigation using pulse-based inverse evolutions
Ivan Henao, Jader P. Santos, Raam Uzdin
Quantum Error Mitigation (QEM) enables the extraction of high-quality results from the presently-available noisy quantum computers. In this approach, the effect of the noise on obs…
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…
Characterizing irreversibility in open quantum systems
T. B. Batalhao, S. Gherardini, J. P. Santos +2
Irreversibility is a fundamental concept with important implications at many levels. It pinpoints the fundamental difference between the intrinsically reversible microscopic equati…
Irreversibility at zero temperature from the perspective of the environemnt
Jader P. Santos, Alberto L. de Paula, Raphael Drumond +2
We address the emergence of entropy production in the non-equilibrium process of an open quantum system from the viewpoint of the environment. By making use of a dilation-based app…
The role of quantum coherence in non-equilibrium entropy production
Jader P. Santos, Lucas C. Céleri, Gabriel T. Landi +1
Thermodynamic irreversibility is well characterized by the entropy production arising from non-equilibrium quantum processes. We show that the entropy production of a quantum syste…
The Wigner Entropy Production Rate
Jader P. Santos, Gabriel T. Landi, Mauro Paternostro
The characterization of irreversibility in general quantum processes is an open problem of increasing techno- logical relevance. Yet, the tools currently available to this aim are…
Microscopic theory of a non-equilibrium open bosonic chain
Jader P. Santos, Gabriel T. Landi
Quantum master equations form an important tool in the description of transport problems in open quantum systems. However, they suffer from the difficulty that the shape of the Lin…
