Dynamics of Loschmidt echoes and fidelity decay

T Gorin, T Prosen, TH Seligman, M Žnidarič - Physics Reports, 2006 - Elsevier
Fidelity serves as a benchmark for the reliability in quantum information processes, and has
recently attracted much interest as a measure of the susceptibility of dynamics to …

Chaos and the quantum phase transition in the Dicke model

C Emary, T Brandes - Physical Review E, 2003 - APS
We investigate the quantum-chaotic properties of the Dicke Hamiltonian; a quantum-optical
model that describes a single-mode bosonic field interacting with an ensemble of N two …

Environment-independent decoherence rate in classically chaotic systems

RA Jalabert, HM Pastawski - Physical review letters, 2001 - APS
We study the decoherence of a one-particle system, whose classical correspondent is
chaotic, when it evolves coupled to a weak quenched environment. This is done by …

Unknown quantum states: the quantum de Finetti representation

CM Caves, CA Fuchs, R Schack - Journal of Mathematical Physics, 2002 - pubs.aip.org
We present an elementary proof of the quantum de Finetti representation theorem, a
quantum analog of de Finetti's classical theorem on exchangeable probability assignments …

An image encryption scheme based on quantum logistic map

A Akhshani, A Akhavan, SC Lim, Z Hassan - Communications in Nonlinear …, 2012 - Elsevier
The topic of quantum chaos has begun to draw increasing attention in recent years. While a
satisfactory definition for it is not settled yet in order to differentiate between its classical …

Decoherence and the Loschmidt echo

FM Cucchietti, DAR Dalvit, JP Paz, WH Zurek - Physical review letters, 2003 - APS
Decoherence causes entropy increase that can be quantified using, eg, the purity ς= T r ρ 2.
When the Hamiltonian of a quantum system is perturbed, its sensitivity to such perturbation …

General relation between quantum ergodicity and fidelity of quantum dynamics

T Prosen - Physical Review E, 2002 - APS
A general relation is derived, which expresses the fidelity of quantum dynamics, measuring
the stability of time evolution to small static variation in the Hamiltonian, in terms of ergodicity …

Continuous quantum measurement and the emergence of classical chaos

T Bhattacharya, S Habib, K Jacobs - Physical review letters, 2000 - APS
We formulate the conditions under which the dynamics of a continuously measured quantum
system becomes indistinguishable from that of the corresponding classical system. In …

Full observation of single-atom dynamics in cavity QED
