Interference and measurement: Changing amplitude phase information to amplitude magnitude information

International Journal of Quantum Information
There are quantum procedures that encode the solutions to a problem in the phases of quantum amplitudes. This happens in some quantum optimization algorithms in which the value of a function to be maximized or minimized is represented by a phase. An example of this is the QAOA algorithm for the MaxCut problem in which one encodes the number of edges ...

Iterative amplitude/phase multiple-symbol differential sphere detection for DAPSK modulated transmissions

, 2012
Differentially encoded and non-coherently detected transceivers exhibit a low complexity, since they dispense with complex channel estimation. Albeit this is achieved at the cost of requiring an increased transmit power, they are particularly beneficial,

Quantum information reclaiming after amplitude damping [PDF]

Journal of Physics A: Mathematical and Theoretical, 2011
We investigate the quantum information reclaim from the environment after amplitude damping has occurred. In particular we address the question of optimal measurement on the environment to perform the best possible correction on two and three dimensional quantum systems.

Temporal Coherence Estimators for GBSAR

Remote Sensing, 2022
Many Ground-Based Synthetic Aperture Radar (GBSAR) applications demand preliminary analysis to select areas with high-quality signal. That is, areas in which the phase can be processed to extract the desired information. The interferometric coherence and

Information transfer in signaling pathways : a study using coupled simulated and experimental data [PDF]

, 2008
Background: The topology of signaling cascades has been studied in quite some detail. However, how information is processed exactly is still relatively unknown.

Multiple Hypothesis Tracking Algorithm Based on Amplitude-Phase Measurement Information Assistance [PDF]

Hangkong bingqi
In range gate pull off (RGPO) jamming scenarios, conventional multiple target tracking algorithm can not effectively distinguish the RGPO deception from real target measurements, resulting in track mis-initialization, increased tracking error, and ...

Amplitude-modulated pulses based phase-sensitive OTDR in distributed sensing

, 2019
The detected frequency response range of phase-sensitive optical time domain reflectometry is limited by the sensing fiber length. In this paper, we demonstrate an amplitude modulated pulses based phase-sensitive OTDR to detect vibrations with high ...

Abnormal P300 in people with high risk of developing psychosis [PDF]

, 2008
Background Individuals with an “at-risk mental state” (or “prodromal” symptoms) have a 20–40% chance of developing psychosis; however it is difficult to predict which of them will become ill on the basis of their clinical symptoms alone.
