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…
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…
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…
New shapes of the rho-meson light-cone distribution amplitudes: how can they influence the B --> rho e nu decay form factors
A. P. Bakulev, S. V. Mikhailov, R. Ruskov
We present new models of the rho-meson leading-twist light-cone distribution amplitudes based on the QCD sum rule approach with nonlocal condensates. Their shapes differ noticeably…
The asymptotics of the transition form factor γγ* -> pi^o and QCD sum rules
A. V. Radyushkin, R. Ruskov
In this paper we present the result of a direct QCD sum rule calculation of the transition form factor γγ* -> pi^o in the region of moderately large invariant momentum Q^2 > 1GeV^2…
