Theoretical development of discrete-modulated continuous-variable quantum key distribution

open access: yesFrontiers in Quantum Science and Technology, 2022
Continuous-variable quantum key distribution offers simple, stable and easy-to-implement key distribution systems. The discrete modulation scheme further reduces the technical difficulty.

Atomic filtering for hybrid continuous-variable/discrete-variable quantum optics

open access: yes, 2014
We demonstrate atomic filtering of frequency-degenerate photon pairs from a sub-threshold optical parametric oscillator (OPO). The filter, a modified Faraday anomalous dispersion optical filter (FADOF), achieves 70% peak transmission simultaneous with 57

On Fractional Orthonormal Polynomials of a Discrete Variable

open access: yesDiscrete Dynamics in Nature and Society, 2015
A fractional analogue of classical Gram or discrete Chebyshev polynomials is introduced. Basic properties as well as their relation with the fractional analogue of Legendre polynomials are presented.

Discrete Scale Relativity And SX Phoenicis Variable Stars

open access: yes, 2009
Discrete Scale Relativity proposes a new symmetry principle called discrete cosmological self-similarity which relates each class of systems and phenomena on a given Scale of nature's discrete cosmological hierarchy to the equivalent class of analogue ...

Variable exponent Hardy spaces associated with discrete Laplacians on graphs

open access: yes, 2017
In this paper we develop the theory of variable exponent Hardy spaces associated with discrete Laplacians on infinite graphs. Our Hardy spaces are defined by square integrals, atomic and molecular decompositions.

Variational Estimates using a Discrete Variable Representation

open access: yes, 2004
The advantage of using a Discrete Variable Representation (DVR) is that the Hamiltonian of two interacting particles can be constructed in a very simple form.

Free space continuous variable Quantum Key Distribution with discrete phases

open access: yesPhysics Open, 2023
Quantum Key Distribution (QKD) offers unconditional security in principle. Many QKD protocols have been proposed and demonstrated to ensure secure communication between two authenticated users.

Discrete conventional signalling of a continuous variable [PDF]

open access: yes, 1998
In aggressive interactions, animals often use a discrete set of signals, while the properties being signalled are likely to be continuous, for example fighting ability or value of victory.

Efficient quantum teleportation of unknown qubit based on DV-CV interaction mechanism

open access: yes, 2018
We propose and develop theory of quantum teleportation of unknown qubit based on interaction mechanism between discrete-variable (DV) and continuous-variable (CV) states on highly transmissive beam splitter (HTBS).

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
