Security of differential phase shift quantum key distribution against individual attacks [PDF]

, 2005
We derive a proof of security for the Differential Phase Shift Quantum Key Distribution (DPSQKD) protocol under the assumption that Eve is restricted to individual attacks.

The Differential Entropy of the Joint Distribution of Eigenvalues of Random Density Matrices

Entropy, 2016
We derive exactly the differential entropy of the joint distribution of eigenvalues of Wishart matrices. Based on this result, we calculate the differential entropy of the joint distribution of eigenvalues of random mixed quantum states, which is induced

Superlattice with hot electron injection: an approach to a Bloch oscillator

, 2002
A semiconductor superlattice with hot electron injection into the miniband is considered. The injection changes the stationary distribution function and results in a qualitative change of the frequency behaviour of the differential conductivity.

Differentiable stochastic halo occupation distribution

Monthly Notices of the Royal Astronomical Society
ABSTRACT In this work, we demonstrate how differentiable stochastic sampling techniques developed in the context of deep reinforcement learning can be used to perform efficient parameter inference over stochastic, simulation-based, forward models.

Zero-sequence compensation method of line longitudinal current differential protection based on 5G distribution network

Diance yu yibiao
Aiming at the problem that the longitudinal current fault of distribution network lines affects the normal power supply, a zero-sequence compensation method of line longitudinal current differential protection based on 5G distribution network is proposed

Line-of-sight quantum key distribution with differential phase shift keying

New Journal of Physics, 2022
Free-space optical (FSO) links offer a practical approach to realize quantum key distribution (QKD) in a global scale. However, when one wants to further extend the distance from the geostationary orbit to the ground, currently known QKD schemes cannot ...

Differential Phase-contrast Interior Tomography

, 2011
Differential phase contrast interior tomography allows for reconstruction of a refractive index distribution over a region of interest (ROI) for visualization and analysis of internal structures inside a large biological specimen. In this imaging mode, x-

Differential distributed cayley space-time codes [PDF]

IEEE Transactions on Wireless Communications, 2009
We consider a wireless relay network with no channel information, which implements differential distributed space-time coding. We propose a coding strategy based on Cayley codes, which yields high data rate codes available for an arbitrary number of relay nodes.

Properties of the integral curve and solving of non-autonomous system of ordinary differential equations

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
In this paper, we consider non-autonomous system of ordinary differential equations. For a given non-autonomous system, we introduce the distribution probability-density function of representative points of the ensemble of Gibbs, possessing all the ...

Compressive sensing based differential protection for distribution grids

International Journal of Electrical Power & Energy Systems
With the significant integration of distributed renewable energy sources into distribution grids, the characteristics of fault current in distribution grids have undergone substantial changes, rendering traditional current protection inadequate to meet ...
