Unveiling and veiling a Schrödinger cat state from the vacuum
Roberto Stassi, Mauro Cirio, Ken Funo +3
Deep in the ultrastrong light-matter coupling regime, it has been predicted that the ground state of a two-level atom interacting with a cavity mode takes the form of a "virtual" S…
General bound on the performance of counter-diabatic driving acting on dissipative spin systems
Ken Funo, Neill Lambert, Franco Nori
Counter-diabatic driving (CD) is a technique in quantum control theory designed to counteract nonadiabatic excitations and guide the system to follow its instantaneous energy eigen…
Shortcuts to Adiabatic Pumping in Classical Stochastic Systems
Ken Funo, Neill Lambert, Franco Nori +1
Adiabatic pumping is characterized by a geometric contribution to the pumped charge, which can be non-zero even in the absence of a bias. However, as the driving speed is increased…
Speeding-up a quantum refrigerator via counter-diabatic driving
Ken Funo, Neill Lambert, Bayan Karimi +3
We study the application of a counter-diabatic driving (CD) technique to enhance the thermodynamic efficiency and power of a quantum Otto refrigerator based on a superconducting qu…
Speed limit for open quantum systems
Ken Funo, Naoto Shiraishi, Keiji Saito
We study the quantum speed limit for open quantum systems described by the Lindblad master equation. The obtained inequality shows a trade-off relation between the operation time a…
Path integral approach to heat in quantum thermodynamics
Ken Funo, H. T. Quan
We study the heat statistics of a quantum Brownian motion described by the Caldeira-Leggett model. By using the path integral approach, we introduce a novel concept of the quantum…
