von Neumann spin measurements with Rashba fields
(IOP Publishing, 2014-01-10)
We show that dynamics in the spin-orbit coupling field simulate the von Neumann measurement of a particle spin. We demonstrate how the measurement influences the spin and coordinate evolution of a particle by comparing two ...
Dual-path methods for propagating quantum microwaves
(IOP Publishing, 2014-01)
We study quantum state tomography, entanglement detection and channel noise reconstruction of propagating quantum microwaves via dual-path methods. The presented schemes make use of the following key elements: propagation ...
