Uncertainty characteristics of generalized quantum measurements [PDF]
, 2002 The effects of any quantum measurement can be described by a collection of measurement operators {M_m} acting on the quantum state of the measured system.

A Testing Method for Shipborne Atomic Gravimeter Based on the Modulated Coriolis Effect
Sensors, 2023 Shipborne atomic gravimeter (SAG) is an instrument that can directly measure absolute gravity in dynamic environments. As a new type of gravity sensor, a standard method for evaluating its detailed performance has not been proposed and the detailed ...

Quantum measurements and contextuality [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019 In quantum physics, the term ‘contextual’ can be used in more than one way. One usage, here called ‘Bell contextual’ since the idea goes back to Bell, is that if A , B and C are three quantum observables, with A compatible (i.e. commuting) with

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.

Conceptual Inadequacy of the Shannon Information in Quantum Measurements [PDF]
, 2001 In a classical measurement the Shannon information is a natural measure of our ignorance about properties of a system. There, observation removes that ignorance in revealing properties of the system which can be considered to preexist prior to and ...

Measuring Quantum Entropy [PDF]
2019 IEEE International Symposium on Information Theory (ISIT), 2019 The entropy of a quantum system is a measure of its randomness, and has applications in measuring quantum entanglement. We study the problem of measuring the von Neumann entropy, $S(ρ)$, and Rényi entropy, $S_α(ρ)$ of an unknown mixed quantum state $ρ$ in $d$ dimensions, given access to independent copies of $ρ$.

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

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.
