Spin-photovoltaic effect in quantum wires due to inter-subband transitions
A. Fedorov, Yu. V. Pershin, C. Piermarocchi
We consider the current induced in a quantum wire by external electromagnetic radiation. The photocurrent is caused by the interplay of spin-orbit interaction (Rashba and Dresselha…
Evaluation of Decoherence for Quantum Control and Computing
Arkady Fedorov, Leonid Fedichkin, Vladimir Privman
Different approaches in quantifying environmentally-induced decoherence are considered. We identify a measure of decoherence, derived from the density matrix of the system of inter…
Additivity of decoherence measures for multiqubit quantum systems
Leonid Fedichkin, Arkady Fedorov, Vladimir Privman
We introduce new measures of decoherence appropriate for evaluation of quantum computing designs. Environment-induced deviation of a quantum system's evolution from controlled dyna…
Measures of Decoherence
Leonid Fedichkin, Arkady Fedorov, Vladimir Privman
Methods for quantifying environmentally induced decoherence in quantum systems are investigated. We formulate criteria for measuring the degree of decoherence and consider several…
