Differential Phase Encoded Plug-and-Play Measurement-Device-Independent Quantum Key Distribution

open access: yesIEEE Transactions on Quantum Engineering
Measurement-device-independent quantum key distribution (MDI-QKD) enhances security by removing vulnerabilities associated with detector side channels. Real-world implementations ofMDI-QKD face practical challenges, such as channel asymmetry and physical

Calculation of Differential Entropy for a Mixed Gaussian Distribution

open access: yesEntropy, 2008
In this work, an analytical expression is developed for the differential entropy of a mixed Gaussian distribution. One of the terms is given by a tabulated function of the ratio of the distribution parameters.

The Riemann tensor for nonholonomic manifolds

open access: yes, 2002
For every nonholonomic manifold, i.e., manifold with nonintegrable distribution, the analog of the Riemann tensor is introduced. It is calculated here for the contact and Engel structures: for the contact structure it vanishes (another proof of Darboux's

A Differential Game with Random Time Horizon and Discontinuous Distribution

open access: yesMathematics, 2020
One class of differential games with random duration is considered. It is assumed that the duration of the game is a random variable with values from a given finite interval.

Performance Pay and the White-Black Wage Gap [PDF]

open access: yes
We show that the reported tendency for performance pay to be associated with greater wage inequality at the top of the earnings distribution applies only to white workers.

Differences in the earnings distribution of self- and dependent emploxed German men - evidence from a quantile regression decomposition analysis [PDF]

open access: yes
This paper uses data from the German Socio-Economic Panel of the years 2000 to 2005 to study the earnings differential between self- and dependent employed German men.

Convergence in Differential Distributions [PDF]

open access: yes, 1995
Differential cryptanalysis is a general attack based on the notion of differences. The success of the attack is derived from the probability of a differential. While it has been observed that the distribution of differentials can be modeled as a Markov chain, there have been few analyses that take advantage of this observation because of the ...

Practical round-robin differential-phase-shift quantum key distribution

open access: yesNew Journal of Physics, 2017
The security of quantum key distribution (QKD) relies on the Heisenberg uncertainty principle, with which legitimate users are able to estimate information leakage by monitoring the disturbance of the transmitted quantum signals.
