Nonlinear quantum metrology of many-body open systems
Mathieu Beau, Adolfo del Campo
We introduce general bounds for the parameter estimation error in nonlinear quantum metrology of many-body open systems in the Markovian limit. Given a -body Hamiltonian and …
Quantum Simulation of Generic Many-Body Open System Dynamics Using Classical Noise
Aurélia Chenu, Mathieu Beau, Jianshu Cao +1
We introduce a scheme for the quantum simulation of many-body decoherence based on the unitary evolution of a stochastic Hamiltonian. Modulating the strength of the interactions wi…
Truncated Calogero-Sutherland models
S. M. Pittman, M. Beau, M. Olshanii +1
A one-dimensional quantum many-body system consisting of particles confined in a harmonic potential and subject to finite-range two-body and three-body inverse-square interactions…
Scaling-up quantum heat engines efficiently via shortcuts to adiabaticity
M. Beau, J. Jaramillo, A. del Campo
The finite-time operation of a quantum heat engine that uses a single particle as a working medium generally increases the output power at the expense of inducing friction that low…
