Measurement-induced quantum walks
Physical Review E, 2022 We investigate a tight binding quantum walk on a graph. Repeated stroboscopic measurements of the position of the particle yield a measured "trajectory", and a combination of classical and quantum mechanical properties for the walk are observed. We explore the effects of the measurements on the spreading of the packet on a one dimensional line, showing

Improved Accuracy for Measurement of Filament Diameter Based on Image-Based Fitting Method
Photonics, 2022 Laser diffraction (LD) has many obvious advantages for measuring. However, the measurement accuracy is limited by a number of factors, such as imaging noise, sensor threshold, and fitting methods.

A Simplified Laser System for Atom Interferometry Based on a Free-Space EOM
Photonics, 2022 In this paper, a compact laser system for 87Rb atom interferometry based on only one free-space electro-optic modulator (EOM) was realized, where repumping and Raman beams were generated with a free-space EOM.

Recovering Classical Dynamics from Coupled Quantum Systems Through Continuous Measurement [PDF]
, 2003 We study the role of continuous measurement in the quantum to classical transition for a system with coupled internal (spin) and external (motional) degrees of freedom.

Formation of strain-induced quantum dots in gated semiconductor nanostructures
AIP Advances, 2015 A long-standing mystery in the field of semiconductor quantum dots (QDs) is: Why are there so many unintentional dots (also known as disorder dots) which are neither expected nor controllable. It is typically assumed that these unintentional dots are due

Exploiting the quantum Zeno effect to beat photon loss in linear optical quantum information processors [PDF]
, 2004 We devise a new technique to enhance transmission of quantum information through linear optical quantum information processors. The idea is based on applying the Quantum Zeno effect to the process of photon absorption.

On the Teleportation of Continuous Variable [PDF]
, 1999 The measurement procedures used in quantum teleportation are analyzed from the viewpoint of the general theory of quantum-mechanical measurements. It is shown that to find the teleported state one should only know the identity resolution (positive ...

Consistent quantum measurements [PDF]
Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 2015 In response to recent criticisms by Okon and Sudarsky, various aspects of the consistent histories (CH) resolution of the quantum measurement problem(s) are discussed using a simple Stern-Gerlach device, and compared with the alternative approaches to the measurement problem provided by spontaneous localization (GRW), Bohmian mechanics, many worlds ...

Nondisturbing quantum measurements [PDF]
Journal of Mathematical Physics, 2010 We consider pairs of discrete quantum observables (POVMs) and analyze the relation between the notions of nondisturbance, joint measurability, and commutativity. We specify conditions under which these properties coincide or differ—depending, for instance, on the interplay between the number of outcomes and the Hilbert space dimension or on algebraic ...
