Quantum Performance of Thermal Machines over Many Cycles
Gentaro Watanabe, B. Prasanna Venkatesh, Peter Talkner +1
The performance of quantum heat engines is generally based on the analysis of a single cycle. We challenge this approach by showing that the total work performed by a quantum engin…
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 …
Shortcuts to adiabaticity in the strongly-coupled regime: nonadiabatic control of a unitary Fermi gas
Shujin Deng, Pengpeng Diao, Qianli Yu +2
Coherent control of complex quantum systems is a fundamental requirement in quantum information processing and engineering. Recently developed notion of shortcut to adiabaticity (S…
Universal Work Fluctuations during Shortcuts To Adiabaticity by Counterdiabatic Driving
Ken Funo, Jing-Ning Zhang, Cyril Chatou +3
Counterdiabatic driving (CD) exploits auxiliary control fields to tailor the nonequilibrium dynamics of a quantum system, making possible the suppression of dissipated work in fini…
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…
Digital Quantum Simulation of Minimal AdS/CFT
L. García-Álvarez, I. L. Egusquiza, L. Lamata +3
We propose the digital quantum simulation of a minimal AdS/CFT model in controllable quantum platforms. We consider the Sachdev-Ye-Kitaev model describing interacting Majorana ferm…
Inhomogeneous quasi-adiabatic driving of quantum critical dynamics in weakly disordered spin chains
Marek M. Rams, Masoud Mohseni, Adolfo del Campo
We introduce an inhomogeneous protocol to drive a weakly disordered quantum spin chain quasi-adiabatically across a quantum phase transition and minimize the residual energy of the…
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…
Anti-Kibble-Zurek Behavior in Crossing the Quantum Critical Point of a Thermally Isolated System Driven by a Noisy Control Field
Anirban Dutta, Armin Rahmani, Adolfo del Campo
We show that a thermally isolated system driven across a quantum phase transition by a noisy control field exhibits anti-Kibble-Zurek behavior, whereby slower driving results in hi…
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…
Shortcuts to adiabaticity by counterdiabatic driving for trapped-ion displacement in phase space
Shuoming An, Dingshun Lv, Adolfo del Campo +1
The application of adiabatic protocols in quantum technologies is severely limited by environmental sources of noise and decoherence. Shortcuts to adiabaticity by counterdiabatic d…
