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…

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…

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…
