Tailoring Quantum Chaos With Continuous Quantum Measurements
Preethi Gopalakrishnan, András Grabarits, Adolfo del Campo
We investigate the role of quantum monitoring in the dynamical manifestations of Hamiltonian quantum chaos. Specifically, we analyze the generalized spectral form factor, defined a…
Shortcuts to Adiabaticity in Driven Open Quantum Systems: Balanced Gain and Loss and Non-Markovian Evolution
S. Alipour, A Chenu, A. T. Rezakhani +1
A universal scheme is introduced to speed up the dynamics of a driven open quantum system along a prescribed trajectory of interest. This framework generalizes counterdiabatic driv…
An Interaction-Driven Many-Particle Quantum Heat Engine: Universal Behavior
Yang-Yang Chen, Gentaro Watanabe, Yi-Cong Yu +2
A quantum heat engine (QHE) based on the interaction driving of a many-particle working medium is introduced. The cycle alternates isochoric heating and cooling strokes with both i…
Probing the Full Distribution of Many-Body Observables by Single-Qubit Interferometry
Zhenyu Xu, Adolfo del Campo
We present an experimental scheme to measure the full distribution of many-body observables in spin systems, both in and out of equilibrium, using an auxiliary qubit as a probe. We…
Extreme Decoherence and Quantum Chaos
Zhenyu Xu, Luis Pedro García-Pintos, Aurélia Chenu +1
We study the ultimate limits to the decoherence rate associated with dephasing processes. Fluctuating chaotic quantum systems are shown to exhibit extreme decoherence, with a rate…
Quantum Speed Limits under Continuous Quantum Measurements
Luis Pedro García-Pintos, Adolfo del Campo
The pace of evolution of physical systems is fundamentally constrained by quantum speed limits (QSL), which have found broad applications in quantum science and technology. We cons…
