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…
Impact of Nonlinearities on Local Kinetic and Thermokinetic Uncertainty Relations in Bosonic Transport
Didrik Palmqvist, Luca Magazzù, Milena Grifoni +1
The precision of transport observables can be bounded by the entropy production and the activity of the transport process via kinetic and thermokinetic uncertainty relations. In li…
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…
A unified diagrammatic approach to quantum transport in few-level junctions for bosonic and fermionic reservoirs: Application to the quantum Rabi model
L. Magazzù, E. Paladino, M. Grifoni
We apply the Nakajima-Zwanzig approach to open quantum systems to study steady-state transport across generic multi-level junctions coupled to bosonic or fermionic reservoirs. The…
Transmission spectra of the driven, dissipative Rabi model in the USC regime
L. Magazzù, P. Forn-Díaz, M. Grifoni
We present theoretical transmission spectra of a strongly driven, damped, flux qubit coupled to a dissipative resonator in the ultrastrong coupling regime. Such a qubit-oscillator…
Transmission spectra of an ultrastrongly coupled qubit-dissipative resonator system
Luca Magazzù, Milena Grifoni
We calculate the transmission spectra of a flux qubit coupled to a dissipative resonator in the ultrastrong coupling regime. Such a qubit-oscillator system constitutes the building…
Generation and stabilization of Bell states via repeated projective measurements on a driven ancilla qubit
L. Magazzù, J. D. Jaramillo, P. Talkner +1
A protocol is proposed to generate Bell states in two non-directly interacting qubits by means of repeated measurements of the state of a central ancilla connected to both qubits.…
Quantum Brownian motion under generalized position measurements: A converse Zeno scenario
L. Magazzù, P. Talkner, P. Hänggi
We study the quantum Brownian motion of a harmonic oscillator undergoing a sequence of generalized position measurements. Our exact analytical results capture the interplay of the…
Probing the strongly driven spin-boson model in a superconducting quantum circuit
L. Magazzù, P. Forn-Díaz, R. Belyansky +6
Quantum two-level systems interacting with the surroundings are ubiquitous in nature. The interaction suppresses quantum coherence and forces the system towards a steady state. Suc…
Quantum resonant activation
Luca Magazzù, Peter Hänggi, Bernardo Spagnolo +1
Quantum resonant activation is investigated for the archetype setup of an externally driven two-state (spin-boson) system subjected to strong dissipation by means of both analytica…
