Dephasing and Renormalization in Quantum Two-Level Systems
Alexander Shnirman, Gerd Schön
Motivated by fundamental questions about the loss of phase coherence at low temperature we consider relaxation, dephasing and renormalization effects in quantum two-level systems w…

Electrical quantum measurement of a two-level system at arbitrary voltage and temperature
A. Shnirman, D. Mozyrsky, I. Martin
We calculate the noise spectrum of the output signal of a quantum detector during continuous measurement of a two-level system (qubit). We generalize the previous results obtained…

Noise and decoherence in quantum two-level systems
Alexander Shnirman, Yuriy Makhlin, Gerd Schön
Motivated by recent experiments with Josephson-junction circuits we reconsider decoherence effects in quantum two-level systems (TLS). On one hand, the experiments demonstrate the…
