Decoherence in qubits due to low-frequency noise
J Bergli, Y M Galperin, B L Altshuler
The efficiency of the future devices for quantum information processing is limited mostly by the finite decoherence rates of the qubits. Recently a substantial progress was achieve…
Decoherence of a qubit by non-Gaussian noise at an arbitrary working point
J. Bergli, Y. M. Galperin, B. L. Altshuler
The decoherence of a qubit due to a classical non-Gaussian noise with correlation time longer than the decoherence time is discussed for arbitrary working points of the qubit. A me…
Non-Gaussian low-frequency noise as a source of qubit decoherence
Y. M. Galperin, B. L. Altshuler, J. Bergli +1
We study decoherence in a qubit with the distance between the two levels affected by random flips of bistable fluctuators. For the case of a single fluctuator we evaluate explicitl…
Orbital ac spin-Hall effect in the hopping regime
O. Entin-Wohlman, A. Aharony, Y. M. Galperin +2
The Rashba and Dresselhaus spin-orbit interactions are both shown to yield the low temperature spin-Hall effect for strongly localized electrons coupled to phonons. A frequency-dep…
Models of environment and T_1 relaxation in Josephson Charge Qubits
Lara Faoro, Joakim Bergli, Boris L. Altshuler +1
A theoretical interpretation of the recent experiments of Astafiev et. al. on the T_1-relaxation rate in Josephson Charge Qubits is proposed. The experimentally observed reproducib…
