Towards Resource Theory of Coherence in Distributed Scenarios

open access: yesPhysical Review X, 2017
The search for a simple description of fundamental physical processes is an important part of quantum theory. One example for such an abstraction can be found in the distance lab paradigm: if two separated parties are connected via a classical channel ...

Planning Coherence Rationales: The Case of the Cameroonian Higher Education Programmes Development

open access: yesJournal of Higher Education Policy and Leadership Studies, 2021
This study discusses programmes planning at the level of the Ministry of Higher Education in Cameroon. It aims at showing the coherence it implies in a context of mismatch between policies and facts. After having shown that coherence follows a rationale,

Compositional resource theories of coherence [PDF]

open access: yesQuantum, 2020
Quantum coherence is one of the most important resources in quantum information theory. Indeed, preventing the loss of coherence is one of the most important technical challenges obstructing the development of large-scale quantum computers.

Quantum coherence as a signature of chaos

open access: yesPhysical Review Research, 2021
We establish a rigorous connection between quantum coherence and quantum chaos by employing coherence measures originating from the resource theory framework as a diagnostic tool for quantum chaos.

Heat Conduction Theory Including Phonon Coherence [PDF]

open access: yesPhysical Review Letters, 2022
Understanding and quantifying the fundamental physical property of coherence of thermal excitations is a long-standing and general problem in physics. The conventional theory, i.e. the phonon gas model, fails to describe coherence and its impact on thermal transport.

Singularities of Partially Polarized Vortex Beams

open access: yesFrontiers in Physics, 2020
Singularities in the polarization state of non-uniform electromagnetic beams have been a topic of both theoretical and practical interest for many years, as have singularities in the correlation functions of random scalar wavefields.

Experimental Direct Measurement of the Relative Entropy of Coherence

open access: yesPhotonics, 2023
Quantum coherence is the most distinguished feature of quantum mechanics, which characterizes the superposition properties of quantum states. It plays a critical role in various fields, ranging from quantum information technology to quantum biology ...

A Review of Ghost Imaging via Sparsity Constraints

open access: yesApplied Sciences, 2018
Different from conventional imaging methods, which are based on the first-order field correlation, ghost imaging (GI) obtains the image information through high-order mutual-correlation of light fields from two paths with an object appearing in only one ...

Catalytic transformations in coherence theory

open access: yesPhysical Review A, 2023
In 2016, A. Winter et al.(Physical Review Letters 116 (12) (2016) 120404) provided an operational meaning to relative entropy of coherence and coherence of formation by introducing coherence distillation and dilation protocol in asymptotic setup. Though relative entropy of coherence introduced in 2014 by T. Baumgratz ( Physical Review Letters 113 (14) (

A quantum random number generator implementation with polarized photons

open access: yesEmergent Scientist, 2017
In this letter, we present an implementation of a random number generator based on photon polarization superposition. We prepare photons in a superposition state of vertical and horizontal polarizations, let them pass through a polarizing beamsplitter ...
