Two-mode Correlation of Microwave Quantum Noise Generated by Parametric Down-Conversion
Two-mode Correlation of Microwave Quantum Noise Parametric Down-Conversion
2010/11/24
In this letter, we report the observation of the correlation between two modes of microwave
radiation resulting from the ampli cation of quantum noise by the Josephson Parametric Converter.This proce...
Reduction of quantum noise in optical interferometers using squeezed light
Reduction quantum noise optical interferometers squeezed light
2010/11/8
We study the photon counting noise in optical interferometers used for gravitational wave detection. In order to reduce quantum noise a squeezed vacuum state is injected into the usually unused input ...
Quantum capacity under adversarial quantum noise: arbitrarily varying quantum channels
Quantum capacity adversarial quantum noise arbitrarily varying quantum channels
2010/10/29
We investigate entanglement transmission over an unknown channel in the presence of a third party (called the adversary), which is enabled to choose the channel from a given set of memoryless but non...
Do revivals of quantum correlations necessarily require quantum noise?
revivals quantum correlations necessarily quantum noise
2010/10/21
We show that in an N-partite system, where each subsystem is subject to a local completely
positive map, total correlations cannot, at later times, exceed their initial value. We then analyze the dyn...
Quantum noise and self-sustained radiation of PT-symmetric systems
Quantum noise self-sustained radiation PT-symmetric systems
2010/3/10
The observation that PT-symmetric Hamiltonians can have real-valued energy levels even if they are non-hermitian has triggered intense activities, with experiments in particular focusing on optical sy...
