Relaxation and Zeno effect in qubit measurements
S. A. Gurvitz, L. Fedichkin, D. Mozyrsky +1
We consider a qubit interacting with its environment and continuously monitored by a detector represented by a point contact. Bloch-type equations describing the entire system of t…
Quantum description of classical apparatus: Zeno effect and decoherence
S. A. Gurvitz
We study the measurement process by treating classical detectors entirely quantum mechanically. As a generic model we use a point-contact detector coupled to an electron in a quant…
Two-electron correlated motion due to Coulomb repulsion
S. A. Gurvitz
A Hubbard-type model is derived from the microscopic Schrödinger equation. We found that additional terms describing direct two-electron transitions must be added to the standard H…
Interference effects in resonant magneto-transport
D. Mozyrsky, L. Fedichkin, S. A. Gurvitz +1
We study non-equilibrium magneto-transport through a single electron transistor or an impurity. We find that due to spin-flip transitions, generated by the spin-orbit interaction,…
Formation and Dynamics of a Schrödinger-Cat State in Continuous Quantum Measurement
G. P. Berman, F. Borgonovi, G. Chapline +5
We consider the process of a single-spin measurement using magnetic resonance force microscopy (MRFM) as an example of a truly continuous measurement in quantum mechanics. This tec…
Dephasing and collapse in continuous measurement of a single system
S. A. Gurvitz
We show that long standing debates on the collapse and the role of the observer in quantum mechanics can be resolved experimentally via a nondistructive continuous monitoring of a…
