Decoherence and Relaxation of a Quantum Bit in the Presence of Rabi Oscillations
نویسنده
چکیده
Dissipative dynamics of a quantum bit driven by a strong resonant field and interacting with a heat bath is investigated. We derive generalized Bloch equations and find modifications of the qubit’s damping rates caused by Rabi oscillations. Nonequilibrium decoherence of a phase qubit inductively coupled to a LC-circuit is considered as an illustration of the general results. Typeset using REVTEX

Rabi oscillations in a large Josephson-junction qubit.
We have designed and operated a circuit based on a large-area current-biased Josephson junction whose two lowest energy quantum levels are used to implement a solid-state qubit. The circuit allows measurement of the qubit states with a fidelity of 85% while providing sufficient decoupling from external sources of relaxation and decoherence to allow coherent manipulation of the qubit state, as d...
متن کاملMesoscopic systems: classical irreversibility and quantum coherence.
Mesoscopic physics is a sub-discipline of condensed-matter physics that focuses on the properties of solids in a size range intermediate between bulk matter and individual atoms. In particular, it is characteristic of a domain where a certain number of interacting objects can easily be tuned between classical and quantum regimes, thus enabling studies at the border of the two. In magnetism, suc...
متن کاملTheory of Weak Continuous Measurements in a Strongly Driven Quantum Bit. Typeset Using Revt E X 1
Continuous spectroscopic measurements of a strongly driven superconduct-ing qubit by means of a high-quality tank circuit (a linear detector) are under study. Output functions of the detector, namely, a spectrum of voltage fluctuations and an impedance, are expressed in terms of the qubit spectrum and magnetic susceptibility. The nonequilibrium spectrum of the current fluctuations in the qubit ...
متن کامل1 Decoherence window and electron - nuclear cross - relaxation in the molecular
Rabi oscillations in the V15 Single Molecule Magnet (SMM) embedded in the surfactant DODA have been studied at different microwave powers. An intense damping peak is observed when the Rabi frequency ΩR falls in the vicinity of the Larmor frequency of protons N ω , while the damping time R τ of oscillations reaches values 10 times shorter than the phase coherence time 2 τ measured at the same te...
متن کاملMaintaining quantum coherence in the presence of noise through state monitoring
Unsharp measurements allow the estimation and tracking of quantum wave functions in real time with minimal disruption of the dynamics. Here we demonstrate that high-fidelity state monitoring, and hence quantum control, is possible, even in the presence of classical dephasing and amplitude noise, by simulating such measurements on a two-level system undergoing Rabi oscillations. Finite estimatio...
