Environment-mediated charging process of quantum batteries

FT Tabesh, FH Kamin, S Salimi - Physical Review A, 2020 - APS
We study the charging process of open quantum batteries mediated by a common
dissipative environment in two different scenarios. In the first case, we consider a quantum …

Information processing at the speed of light

M AbuGhanem - Frontiers of Optoelectronics, 2024 - Springer
In recent years, quantum computing has made significant strides, particularly in light-based
technology. The introduction of quantum photonic chips has ushered in an era marked by …

Environment-mediated entropic uncertainty in charging quantum batteries

ML Song, LJ Li, XK Song, L Ye, D Wang - Physical Review E, 2022 - APS
We studied the dynamics of entropic uncertainty in Markovian and non-Markovian systems
during the charging of open quantum batteries (QBs) mediated by a common dissipation …

Energetic and entropic effects of bath-induced coherences

CL Latune, I Sinayskiy, F Petruccione - Physical Review A, 2019 - APS
The unavoidable interaction of a quantum system with its surrounding environment (its bath)
is not always detrimental for quantum properties. For instance, under some specific …

Thermodynamics from indistinguishability: Mitigating and amplifying the effects of the bath

CL Latune, I Sinayskiy, F Petruccione - Physical Review Research, 2019 - APS
Rich quantum effects emerge when several quantum systems are indistinguishable from the
point of view of the bath they interact with. In particular, delocalized excitations …

Non-Markovianity through quantum coherence in an all-optical setup

MHM Passos, PC Obando, WF Balthazar, FM Paula… - Optics letters, 2019 - opg.optica.org
We propose an all-optical experiment to quantify non-Markovianity in an open quantum
system through quantum coherence of a single quantum bit. We use an amplitude damping …

Optical simulation of a quantum thermal machine

MHM Passos, AC Santos, MS Sarandy, JAO Huguenin - Physical Review A, 2019 - APS
We introduce both a theoretical and an experimental scheme for simulating a quantum
thermal engine through an all-optical approach, with the behavior of the working substance …

Spin-orbit states

WF Balthazar, DG Braga, VS Lamego, MHM Passos… - Physical Review A, 2021 - APS
We propose an all-optical setup to produce a wide class of X states with an intense laser
beam using spin-orbit modes. In order to characterize such simulated states, we …

Classical analog of quantum contextuality in spin-orbit laser modes

MHM Passos, WF Balthazar, JA de Barros, CER Souza… - Physical Review A, 2018 - APS
We experimentally observed the violation of Kujula–Dzhafarov noncontextuality inequalities
by nonseparable spin-orbit laser modes. Qubits are encoded on polarization and transverse …

Efficient quantum key distribution against collective noise using polarization and transverse spatial mode of photons

PL Guo, C Dong, Y He, F Jing, WT He, BC Ren… - Optics …, 2020 - opg.optica.org
Channel noise is the main issue which reduces the efficiency of quantum communication.
Here we present an efficient scheme for quantum key distribution against collective-rotation …
