Decoherence of a Measure of Entanglement
D. Tolkunov, V. Privman, P. K. Aravind
We demonstrate by an explicit model calculation that the decay of entanglement of two two-state systems (two qubits) is governed by the product of the factors that measure the degr…
Influence of Nuclear Spin Polarization on Quantum Wire Conductance
James A. Nesteroff, Yuriy V. Pershin, Vladimir Privman
In this work, we study a possibility to measure the transverse and longitudinal relaxation times of a collection of polarized nuclear spins located in the region of a quantum wire…
Studies of Short-Time Decoherence for Evaluation of Quantum Computer Designs
Vladimir Privman, Denis Tolkunov
We review our recent results on short time approximations, with emphasis on applications for which the system-environment interactions involve a general non-Hermitian system operat…
Models of Short-Time Qubit Decoherence
Dmitry Solenov, Vladimir Privman
We compare approaches to evaluation of decoherence at low temperatures in two-state quantum systems weakly coupled to the environment. By analyzing an exactly solvable model, we de…
Short-Time Decoherence for General System-Environment Interactions
Denis Tolkunov, Vladimir Privman
Short time approximation is developed for system-environmental bath mode interactions involving a general non-Hermitian system operator , and its conjugate, , in orde…
Polarization of Nuclear Spins from the Conductance of Quantum Wire
James A. Nesteroff, Yuriy V. Pershin, Vladimir Privman
We devise an approach to measure the polarization of nuclear spins via conductance measurements. Specifically, we study the combined effect of external magnetic field, nuclear spin…
