Journal ArticleDOI
Rashba spin precession in a magnetic field
TL;DR: In this article, an external magnetic field perpendicular to the plane of the electron gas is applied to the two-dimensional electron gas in order to enhance the lateral confining potential of the system.
Journal ArticleDOI
Sensitivity and back action in charge qubit measurements by a strongly coupled single-electron transistor
TL;DR: In this article, the authors derived a Lindblad-form master equation and a corresponding quantum trajectory model for continuous measurement of the charge qubit by a single-electron transistor (SET) operating in the sequential-tunneling regime.
Journal ArticleDOI

TL;DR: In this article, a new model for the continuous measurement of a coupled quantum dot charge qubit is presented, which is achieved by embedding the detector in an equivalent circuit for measurement.
Journal ArticleDOI
Non-ideal monitoring of a qubit state using a quantum tunnelling device
TL;DR: In this paper, a model for non-ideal monitoring of the state of a coupled quantum dot qubit by a quantum tunnelling device has been proposed, which allows realistically available measurement results to be related to the quantum system (qubit).
Journal ArticleDOI
Absorptive Quantum Measurements via Coherently Coupled Quantum Dots
TL;DR: In this article, an absorptive measurement scheme via coupled quantum dots based on studies of the quantum dynamics of coherently coupled dots is proposed, which is described through a Markov master equation that is related to a measurable quantity, the current.
