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…
Relaxation and Zeno effect in qubit measurements
S. A. Gurvitz, L. Fedichkin, D. Mozyrsky +1
We consider a qubit interacting with its environment and continuously monitored by a detector represented by a point contact. Bloch-type equations describing the entire system of t…
