Witnessing effective entanglement over a 2km fiber channel [PDF]

, 2010
We present a fiber-based continuous-variable quantum key distribution system. In the scheme, a quantum signal of two non-orthogonal weak optical coherent states is sent through a fiber-based quantum channel. The receiver simultaneously measures conjugate

DISTRIBUTION OF FIBER LENGTH OF KOZO

Journal of the Japanese Technical Association of the Pulp and Paper Industry, 1952
We treated the distributions of fiber length on the stand point of inductive statistics, and found to resemble the normal frequency distribution.We calculated the rejection limit under definite level of significance, and far we considered the difference between each samples.

Fast Characterization of Dispersion and Dispersion Slope of Optical Fiber Links using Spectral Interferometry with Frequency Combs [PDF]

, 2009
We demonstrate fast characterization (~1.4 microseconds) of both the dispersion and dispersion slope of long optical fiber links (~25 km) using dual quadrature spectral interferometry with an optical frequency comb.

Investigation of a Multivariate Correction Method for HVI Fibrogram Measurements

Agronomy, 2022
Cotton fiber length parameters are used across the cotton industry to select elite germplasm, purchase cotton bales and manage mill throughput. The High Volume Instrument (HVI) provides the most commonly used fiber length parameters, upper half mean ...

Spherical averages in the space of marked lattices [PDF]

, 2016
A marked lattice is a $d$-dimensional Euclidean lattice, where each lattice point is assigned a mark via a given random field on ${\mathbb Z}^d$. We prove that, if the field is strongly mixing with a faster-than-logarithmic rate, then for every given ...

Depolarization of light due to the optical Kerr effect in low-birefringence single-mode fibers [PDF]

, 1986
The evolution of the state of polarization of an electromagnetic field propagating in a low-birefringence single-mode fiber in the presence of the nonlinear interaction associated with the optical Kerr effect is investigated.

Quantum key distribution over 122 km of standard telecom fiber

, 2004
We report the first demonstration of quantum key distribution over a standard telecom fiber exceeding 100 km in length. Through careful optimisation of the interferometer and single photon detector, we achieve a quantum bit error ratio of 8.9% for a ...
