Controlling sudden transition from classical to quantum decoherence via non-equilibrium environments
Publikováno v:
New Journal of Physics, Vol 22, Iss 3, p 033039 (2020)
We investigate the freezing and sudden transition in the dynamical behavior of quantum and classical correlations in a system composed of two identical non-interacting qubits locally subjected to their own non-equilibrium environments. In contrast to

Correlations in the open quantum systems manifest a rich phenomenology under the influence of various physical sources of noise. We theoretically study the dynamics of quantum correlations and their classical counterparts in a two-qubit system, measu

We investigate the control over surface plasmon polaritons (SPPs) using the interface between a four-level tripod-type atomic system and a nanocomposite medium under the effect of spontaneously generated coherence (SGC). The absorption and dispersion

We propose a protocol to protect the quantum states and entanglements from finite-temperature thermal noise via quantum gates. Compared to the common protocols protecting the quantum states and entanglements by using weak measurements and their rever
