Submitted for the MAR11 Meeting of The American Physical Society Suppression of Decoherence and Disentanglement in Qubits via the Exchange Interaction1 AMRIT DE, DONG ZHOU, ROBERT JOYNT, Department of Physics, University of WisconsinMadison, WI-53706 — We show that the decoherence and disentanglement for a pair of interacting qubits can be suppressed by the exchange interaction in the presence ...
متن کاملPerspectives on Solid-State Flying Qubits
The quest for quantum-computing capable architectures has recently focused on solid-state implementations, since they seem more prone to meet the required criteria [1] of scalability and integrability than alternative approaches like the ones based on nuclear magnetic resonance, ion traps or quantum electrodynamics techniques [2]. In many proposals different components of a quantum-computing sy...

In this study, we consider a composed system consisting of two identical non-interacting subsystems. Each sub-system is made of a moving qubit into a leaky cavity. The study of the dynamic of the composed system revealed that compared with the stationary qubits, entanglement, quantum discord and coherence between two moving qubits remained close to their initial values as time went by. In parti...
متن کاملSuper operator Technique in Investigation of the Dynamics of a Two Non-Interacting Qubit System Coupled to a Thermal Reservoir
In this paper, we clarify the applicability of the super operator technique for describing the dissipative quantum dynamics of a system consists of two qubits coupled with a thermal bath at finite temperature. By using super operator technique, we solve the master equation and find the matrix elements of the density operator. Considering the qubits to be initially prepared in a general mixed st...
متن کاملA quantitative witness for Greenberger-Horne-Zeilinger entanglement
Along with the vast progress in experimental quantum technologies there is an increasing demand for the quantification of entanglement between three or more quantum systems. Theory still does not provide adequate tools for this purpose. The objective is, besides the quest for exact results, to develop operational methods that allow for efficient entanglement quantification. Here we put forward ...
