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…

Thermometric machine for ultraprecise thermometry of low temperatures
Ivan Henao, Karen V. Hovhannisyan, Raam Uzdin
Thermal equilibrium states are exponentially hard to distinguish at very low temperatures, making equilibrium quantum thermometry in this regime a formidable task. We present a the…

Catalytic transformations with finite-size environments: applications to cooling and thermometry
Ivan Henao, Raam Uzdin
The laws of thermodynamics are usually formulated under the assumption of infinitely large environments. While this idealization facilitates theoretical treatments, real physical s…
