Non-classical photon statistics in frequency-modulated double quantum dot cavity systems
T. Mihaescu, A. Isar, M. A. Macovei
The quantum dynamics of a double quantum dot two-level system, coupled to a leaking microwave resonator mode, is theoretically investigated. The double quantum dot is driven by app…
Dynamical Evolution of Quantum Correlations and Decoherence in Coupled Oscillators Interacting with a Thermal Reservoir
Somayeh Mehrabankar, Farkhondeh Abbasnezhad, Davood Afshar +1
We investigate the dynamical evolution of quantum discord, entanglement and purity in an open quantum system of two coupled asymmetric harmonic oscillators interacting with a therm…
Two-quanta processes in coupled double-quantum-dot cavity systems
Tatiana Mihaescu, Aurelian Isar, Mihai A Macovei
The quantum dynamics of a compound sample consisting from a semiconductor double quantum dot (DQD) system non-linearly coupled with a leaking single-mode micro-resonator is theoret…
The effect of noisy environment on Secure Quantum Teleportation of uni-modal Gaussian states
Somayeh Mehrabankar, Payman Mahmoudi, Farkhondeh Abbasnezhad +2
Quantum communication networks can be built on quantum teleportation, which is the transmission of an unknown quantum state from a sending station to a remote receiving station sup…
Steering witnesses for unknown Gaussian quantum states
Tatiana Mihaescu, Hermann Kampermann, Aurelian Isar +1
We define and fully characterize the witnesses based on second moments detecting steering in Gaussian states by means of Gaussian measurements. All such tests, which arise from lin…
Dynamics of quantum discord of two coupled spin-1/2 subjected to time-dependent magnetic fields
Roberto Grimaudo, Tatiana Mihaescu, Aurelian Isar +2
We describe the dynamics of quantum discord of two interacting spin-1/2 subjected to controllable time-dependent magnetic fields. The exact time evolution of discord is given for v…
