Quantum Zeno stabilization in weak continuous measurement of two qubits
Rusko Ruskov, Alexander N. Korotkov, Ari Mizel
We have studied quantum coherent oscillations of two qubits under continuous measurement by a symmetrically coupled mesoscopic detector. The analysis is based on a Bayesian formali…
Signatures of quantum behavior in single-qubit weak measurements
Rusko Ruskov, Alexander N. Korotkov, Ari Mizel
With the recent surge of interest in quantum computation, it has become very important to develop clear experimental tests for ``quantum behavior'' in a system. This issue has been…
Efficient algorithm for current spectral density calculation in single-electron tunneling and hopping
Viktor A. Sverdlov, Yusuf A. Kinkhabwala, Alexander N. Korotkov
This write-up describes an efficient numerical method for the Monte Carlo calculation of the spectral density of current in the multi-junction single-electron devices and hopping s…
Squeezing of a nanomechanical resonator by quantum nondemolition measurement and feedback
Rusko Ruskov, Keith Schwab, Alexander N. Korotkov
We analyze squeezing of the nanoresonator state produced by periodic measurement of position by a quantum point contact or a single-electron transistor. The mechanism of squeezing…
Noisy quantum measurement of solid-state qubits: Bayesian approach
Alexander N. Korotkov
We discuss a recently developed formalism which describes the quantum evolution of a solid-state qubit due to its continuous measurement. In contrast to the conventional ensemble-a…
Quantum feedback control of a solid-state two-level system
Rusko Ruskov, Alexander N. Korotkov
We have studied theoretically the basic operation of a quantum feedback loop designed to maintain the desired phase of quantum coherent oscillations in a two-level system. Such fee…
