Quantitative Evaluation of Decoherence and Applications for Quantum-Dot Charge Qubits
L. Fedichkin, V. Privman
We review results on evaluation of loss of information in quantum registers due to their interactions with the environment. It is demonstrated that an optimal measure of the level…
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…
Initial Decoherence of Open Quantum Systems
Vladimir Privman
We present a new short-time approximation scheme for evaluation of decoherence. At low temperatures, the approximation is argued to apply at intermediate times as well. It then pro…
Semiconductor quantum computer design with 100 nm separation of nuclear-spin qubits
Vladimir Privman, Dima Mozyrsky
We combine elements of the 1998 quantum computing proposals by Privman, Vagner and Kventsel, and by Kane, with the new idea of nuclear-spin qubit interactions mediated indirectly v…
Decoherence and Measurement in Open Quantum Systems
Vladimir Privman, Dima Mozyrsky
We review results of a recently developed model of a microscopic quantum system interacting with the macroscopic world components which are modeled by collections of bosonic modes.…
Adiabatic Decoherence
D. Mozyrsky, V. Privman
We study a general quantum system interacting with environment modeled by the bosonic heat bath of Caldeira and Leggett type. General interaction Hamiltonians are considered that c…
