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…

Collective Decoherence of Nuclear Spin Clusters

A. Fedorov, L. Fedichkin

The problem of dipole-dipole decoherence of nuclear spins is considered for strongly entangled spin cluster. Our results show that its dynamics can be described as the decoherence…

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…

Decoherence Rate of Semiconductor Charge Qubit Coupled to Acoustic Phonon Reservoir

L. Fedichkin, A. Fedorov

We analyze decoherence of an electron in a double-dot due to the interaction with acoustic phonons. For large tunneling rates between the quantum dots, the main contribution to dec…

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…
