Thermalization and dephasing in an isolated system of coupled qubits
Jukka P. Pekola, Bayan Karimi
A system evolving unitarily does not dephase or thermalize by definition. Yet, if one considers a part of a unitary system, situation is different. Here we analyze an isolated set…
Heat transport in driven quantum systems: Comparison between the Floquet-Redfield equation and the master equation in the instantaneous eigenbasis
Luca Magazzù, Christoforus Dimas Satrya, Aleksandr S. Strelnikov +2
We provide a comprehensive study of heat transport in periodically driven quantum systems using a master equation approach in the Floquet basis. Starting from the exact, formal exp…
Probing strongly driven and strongly coupled superconducting qubit-resonator system
Oleh V. Ivakhnenko, Christoforus Dimas Satrya, Yu-Cheng Chang +5
We investigated a strongly driven qubit strongly connected to a quantum resonator. The measured system was a superconducting flux qubit coupled to a coplanar-waveguide resonator wh…
A blueprint for experiments exploring the Poincaré quantum recurrence theorem
Bayan Karimi, Xuntao Wu, Andrew N. Cleland +1
The quantum form of the Poincaré recurrence theorem stipulates that a system with a time-independent Hamiltonian and discrete energy levels returns arbitrarily close to its initial…
Thermal rectification in a qubit-resonator system
Luca Magazzù, Elisabetta Paladino, Jukka P. Pekola +1
A qubit-oscillator junction connecting as a series two bosonic heat baths at different temperatures can display heat valve and diode effects. In particular, the rectification can c…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Strong-coupling quantum thermodynamics using a superconducting flux qubit
Rishabh Upadhyay, Bayan Karimi, Diego Subero +4
Thermodynamics in quantum circuits aims to find improved functionalities of thermal machines, highlight fundamental phenomena peculiar to quantum nature in thermodynamics, and poin…
Thermal spectrometer for superconducting circuits
Christoforus Dimas Satrya, Yu-Cheng Chang, Aleksandr S. Strelnikov +5
Superconducting circuits provide a versatile and controllable platform for studies of fundamental quantum phenomena as well as for quantum technology applications. A conventional t…
Thermometry Based on a Superconducting Qubit
Dmitrii S. Lvov, Sergei A. Lemziakov, Elias Ankerhold +2
We report temperature measurements using a transmon qubit by detecting the population of its first three energy levels, after applying a sequence of -pulses and performing proje…
Thermalization via three-wave mixing
Jukka P. Pekola, Bayan Karimi
We discuss thermalization in a multimode quantum cavity under unitary evolution. According to general principles, an isolated system with quadratic couplings does not exhibit therm…
Dicke superradiant enhancement of the heat current in circuit QED
Gian Marcello Andolina, Paolo Andrea Erdman, Frank Noé +2
Collective effects, such as Dicke superradiant emission, can enhance the performance of a quantum device. Here, we study the heat current flowing between a cold and a hot bath thro…
