Generating Sustained Coherence in a Quantum Memory for Retrieval at Times of Quantum Revival

Atoms, 2022
We study the time degradation of quantum information stored in a quantum memory device under a dissipative environment in a parameter range which is experimentally relevant.

Quantum revival patterns from classical phase-space trajectories [PDF]

Physical Review A, 2019
A general semiclassical method in phase space based on the final value representation of the Wigner function is considered that bypasses caustics and the need to root-search for classical trajectories.

Entanglement dynamics in a three-atom multi-photon nonlinear JCM with f-deformed Kerr nonlinearity [PDF]

Scientific Reports
In this paper, we explore the atomic population inversion and entanglement dynamics of a quantum system consisting of three identical two-level atoms interacting with a single-mode cavity field.

Topological Effects of a Spiral Dislocation on Quantum Revivals

Universe, 2022
We analyse the influence of spiral dislocation topology on the revival time for the harmonic oscillator, for a particle confined to one-dimensional quantum ring, and a two-dimensional quantum ring. We first investigate the effects of a cut-off point that

Information scrambling versus quantum revival through the lens of operator entanglement

Journal of High Energy Physics, 2022
In this paper, we look for signatures of quantum revivals in two-dimensional conformal field theories (2d CFTs) on a spatially compact manifold by using operator entanglement.

Quantum information scrambling in quantum many-body scarred systems

Physical Review Research, 2022
Quantum many-body scarred systems host special nonthermal eigenstates that support periodic revival dynamics and weakly break the ergodicity. Here, we study the quantum information scrambling dynamics in quantum many-body scarred systems, with a focus on
