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…
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…
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…
Quantum Correlation Dynamics in Controlled Two-Coupled-Qubit Systems
Iulia Ghiu, Roberto Grimaudo, Tatiana Mihaescu +2
We study and compare the time evolutions of concurrence and quantum discord in a driven system of two interacting qubits prepared in a generic Werner state. The~corresponding quant…
Detecting entanglement of unknown continuous variable states with random measurements
Tatiana Mihaescu, Hermann Kampermann, Giulio Gianfelici +2
We explore the possibility of entanglement detection in continuous variable systems by entanglement witnesses based on covariance matrices, constructible from random homodyne measu…
Suppression of entanglement in two-mode Gaussian open systems
Tatiana Mihaescu, Aurelian Isar
We study the evolution of the entanglement of two independent bosonic modes embedded in a thermal environment, in the framework of the theory of open quantum systems. As a measure…
