Radiation statistics of a degenerate parametric oscillator at threshold

open access: yesSciPost Physics, 2023
As a function of the driving strength, a degenerate parametric oscillator exhibits an instability at which spontaneous oscillations occur. Close to threshold, both the nonlinearity as well as fluctuations are vital to the accurate description of the ...

Photocount statistics of the Josephson parametric amplifier

open access: yesPhysical Review Research, 2022
Parametric amplifiers are known to squeeze the vacuum state of the electromagnetic field, thus the statistics of the photocounts at their output should be that of squeezed vacuum.

A Novel Statistical Multi-Channel Busy Recognition Mechanism in the MAC Layer for Airborne Tactical Networks

open access: yesIEEE Access, 2017
The traditional MAC protocol in ad hoc networks includes carrier sensing to judge the busy/idle state of a channel. However, in airborne tactical networks, the results of carrier sensing are usually inaccurate due to the wide distribution of nodes, large
