SCA with Magnitude Squared Coherence [PDF]
Magnitude Squared Coherence is a signal processing tool that indicates how well two time domain signals match one with the other by tracking linear dependencies in their spectral decomposition. SCAN was the first way to use it as a SCA. This paper introduces two ways of using the Magnitude Squared Coherence in Side Channel Analysis. The first way is to

Generation and Propagation of Partially Coherent Power-Exponent-Phase Vortex Beam
We report on a partially coherent power-exponent-phase vortex beam (PC-PEPV), whose spatial coherence is controllable and the initial phase exhibits a periodic power exponential change.

Clock transition by continuous dynamical decoupling of a three-level system [PDF]
We present a novel continuous dynamical decoupling scheme for the construction of a robust qubit in a three-level system. By means of a clock transition adjustment, we first show how robustness to environmental noise is achieved, while eliminating drive ...

Introduction: The vasti muscles have to work in concert to control knee joint motion during movements like walking, running, or squatting. Coherence analysis between surface electromyography (EMG) signals is a common technique to study muscle ...

Coherent phase transfer for real-world twin-field quantum key distribution
Exploiting technologies derived from the optical clocks community, the authors demonstrate a setup for twin-field QKD which extends the coherence times by three orders of magnitude, overcoming the main challenge towards real-world implementation.

Design of a Direction-of-Arrival Estimation Method Used for an Automatic Bearing Tracking System
In this paper, we introduce a sub-band direction-of-arrival (DOA) estimation method suitable for employment within an automatic bearing tracking system. Inspired by the magnitude-squared coherence (MSC), we extend the MSC to the sub-band and propose the ...

The coherence time of sunlight in the context of natural and artificial light-harvesting
The suggestion that quantum coherence might enhance biological processes such as photosynthesis is not only of fundamental importance but also leads to hopes of developing bio-inspired ‘green’ quantum technologies that mimic nature. A key question is how

Atom laser coherence and its control via feedback [PDF]
We present a quantum-mechanical treatment of the coherence properties of a single-mode atom laser. Specifically, we focus on the quantum phase noise of the atomic field as expressed by the first-order coherence function, for which we derive analytical ...

For solid-state spin systems, unwanted interactions with surrounding spin baths and inhomogeneity are ubiquitous challenges. In defect spin systems, part of this challenge is that the process of generating the desired defect often involves creating ...

Can InSAR Coherence and Closure Phase Be Used to Estimate Soil Moisture Changes?
We studied the influence of the statistical properties of soil moisture changes on the Interferometric Synthetic Aperture Radar (InSAR) coherence and closure phase to determine whether the InSAR coherence and closure phase can be used to estimate soil ...
