The use of the output states generated by the broadcasting of entanglement in quantum teleportation
Iulia Ghiu, Catalina Cirneci, George Alexandru Nemnes
In this article, we find a theorem that gives a relation between the maximal fidelity of teleportation and the concurrence of the inseparable state used as a quantum channel in…
Investigation of bi-particle states in gate-array-controlled quantum-dot systems aided by machine learning techniques
G. A. Nemnes, T. L. Mitran, A. T. Preda +3
Quantum computing architectures require an accurate and efficient description in terms of many-electron states. Recent implementations include quantum dot arrays, where the ground…
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…
Determining the output port from the distance
Iulia Ghiu
In this paper we discuss the following scenario. Suppose that two distant observers share an entangled state of two -level systems. The two observers, Alice and Bob, have to sen…
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…
Simultaneous sorting many quDits using different input ports
Iulia Ghiu
Quantum sorter has gained a lot of attention during the last years due to its wide application in quantum information processing and quantum technologies. A challenging task is the…
