General communication enhancement via the quantum switch

Z Wu, J Fullwood, Z Ma, SQ Zhou, Q Zhao, G Chiribella - Physical Review A, 2025 - APS
Recent studies have shown that quantum information may be effectively transmitted by a
finite collection of completely depolarizing channels in a coherent superposition of different …

Boosting entanglement growth of many-body localization by superpositions of disorder

JD Lin, YN Chen - Physical Review A, 2023 - APS
Many-body localization (MBL) can occur when strong disorders prevent an interacting
system from thermalization. To study the dynamics of such systems, performing an ensemble …

Super-Extensive Scaling in 1D Spin Chain Quantum Battery

A Ali, S Elghaayda, S Al-Kuwari, MI Hussain… - arxiv preprint arxiv …, 2024 - arxiv.org
We investigate the performance of a one-dimensional (1D) spin-$1/2$ Heisenberg $ XY-
\Gamma (\gamma) $ quantum chain as a working medium for a quantum battery (QB) and …

Positive and non-positive measurements in energy extraction from quantum batteries

P Chaki, A Bhattacharyya, K Sen, U Sen - arxiv preprint arxiv:2404.18745, 2024 - arxiv.org
We extend the concept of stochastic energy extraction from quantum batteries to the
scenario where both positive operator-valued (POV) and physically realizable non-positive …

Charging a Quantum Battery Mediated by Parity-Deformed Fields

B Mojaveri, RJ Bahrbeig, MA Fasihi - arxiv preprint arxiv:2405.11356, 2024 - arxiv.org
We study the effect of parity deformation of the environmental field modes on the wireless
charging performance of a qubit-based open quantum battery (QB) consisting of a qubit …
