چکیده
We have analyzed theoretically the operation of the Bayesian quantum feedback of a solid-state qubit, designed to maintain perfect coherent oscillations in the qubit for arbitrarily long time. In particular, we have studied the feedback efficiency in presence of dephasing environment and detector nonideality. Also, we have analyzed the effect of qubit parameter deviations and studied the quantum feedback control of an energyasymmetric qubit.

Non-ideal quantum feedback of a solid-state qubit
We have analyzed the operation of the Bayesian quantum feedback of a solid-state qubit, designed to maintain perfect coherent oscillations in the qubit for arbitrarily long time. In particular, we have studied the feedback efficiency in presence of dephasing environment and detector nonideality. Also, we have investigated the effect of qubit parameter deviation.
متن کاملQuantum Feedback Control of a Solid-State Qubit
The principle of feedback control is used in a wide variety of physical and engineering problems. For example, it can be applied in a straightforward way to tune the oscillation phase of a harmonic oscillator in order to achieve a desired synchronization. An intriguing and fundamental question is whether continuous feedback can be used to control quantum systems; for instance, if it is possible...

We propose an experiment on quantum feedback control of a solid-state qubit, which is within the reach of the present-day technology. Similar to an earlier proposal fR. Ruskov and A. N. Korotkov, Phys. Rev. B 66, 041401sRd s2002dg, the feedback loop is used to maintain coherent oscillations in a qubit for an arbitrarily long time; however, this is done in a significantly simpler way, which ease...
متن کاملQuantum feedback of a double-dot qubit
We discuss an experimental proposal on quantum feedback control of a double-dot qubit, which seems to be within the reach of the present-day technology. Similar to the earlier proposal, the feedback loop is used to maintain the coherent oscillations in the qubit for an arbitrary long time; however, this is done in a significantly simpler way. The main idea is to use the quadrature components of...
متن کاملQuantum feedback control of a superconducting qubit: Persistent Rabi oscillations
The act of measurement bridges the quantum and classical worlds by projecting a superposition of possible states into a single, albeit probabilistic, outcome. The time-scale of this “instantaneous” process can be stretched using weak measurements so that it takes the form of a gradual random walk towards a final state. Remarkably, the interim measurement record is sufficient to continuously tra...
