Bound state and non-Markovian dynamics of a quantum emitter around a surface plasmonic nanostructure

SS Wen, YG Huang, XY Wang, J Liu, Y Li, XE Quan… - Optics …, 2020 - opg.optica.org
A bound state between a quantum emitter (QE) and surface plasmon polaritons (SPPs) can
be formed, where the excited QE will not relax completely to its ground state and is partially …

Controllable dissipation of a qubit coupled to an engineering reservoir

HZ Shen, S Xu, S Yi, XX Yi - Physical Review A, 2018 - APS
The dynamics and non-Markovianity of an atomic impurity qubit (AIQ) immersed in a
structured environment is explored where the AIQ is driven by a two-dimensional field and …

Canonical versus noncanonical equilibration dynamics of open quantum systems

CJ Yang, JH An, HG Luo, Y Li, CH Oh - Physical Review E, 2014 - APS
In statistical mechanics, any quantum system in equilibrium with its weakly coupled reservoir
is described by a canonical state at the same temperature as the reservoir. Here, by studying …

[HTML][HTML] Remote sensing and faithful quantum teleportation through non-localized qubits
