Perfect state transfer and maximal entanglement in a trimer of three-level systems

A Aiyejina, E Wyke, R Andrews, AD Greentree - Physical Review A, 2023 - APS
We analyze a quantum wire that consists of a linear chain of three qutrits with nearest-
neighbor interactions and detuning on the central qutrit. We derive the detuning conditions …

Entropy exchange and thermal fluctuations in the Jaynes–Cummings model

JD Castaño-Yepes - The European Physical Journal Plus, 2022 - Springer
The time dependence of the quantum entropy for a two-level atom interacting with a single-
cavity mode is computed using the Jaynes–Cummings model, when the initial state of the …

Double-excitation transfer in dimer and trimer three-level systems using laser pulses and single photons

A Aiyejina, E Wyke, R Andrews, AD Greentree - JOSA B, 2024 - opg.optica.org
We derive and simulate the wavefunctions and double-excitation probabilities for dimer and
trimer three-level systems. Perfect state transfer occurs for pulse strengths that are odd …

Protecting quantum entanglement in thermal reservoir by detuning

C Zhang, J Yang - Physica Scripta, 2022 - iopscience.iop.org
In this work, the quantum entanglement dynamics of a two-atom system in the thermal
reservoir is investigated. An analytical solution of the single atom in the thermal reservoir …

Effects of dissipation induced blockade on the dynamics of two qubits without direct interaction

EM Sampuli, Y Wang, Y Xia, J Song - Optics Express, 2021 - opg.optica.org
We study the effects of dissipation induced blockade on the dynamics of an open quantum
system having two qubits in nonequilibrium independent baths. The qubits are driven by a …
