Large-angle scattered light measurements for quantum-noise filter cavity design studies
Large-angle scattered light measurements quantum-noise filter cavity design studies Optics
2012/4/24
Optical loss from scattered light could limit the performance of quantum-noise filter cavities being considered for an upgrade to the Advanced LIGO gravitational-wave detectors. This paper describes i...
The efficiency of extracting single atoms or molecules from an ultracold bosonic reservoir is theoretically investigated for a protocol based on lasers, coupling the hyperfine state in which the atoms...
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...
360km Field Transmission of 10 Gbit/s Stream Cipher by Quantum Noise for Optical Network
Fiber optics communication Optical security encryption
2015/6/10
Secure optical transmission experiment is demonstrated using a stream cipher by quantum noise. The bit error rates of a 10Gbit/s signal through 360km fiber for authentic receiver and eavesdropper are ...
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...
Quantum-noise encryption using a spectral encoding protocol
Quantum-noise encryption spectral encoding protocol
2015/7/31
An innovative spectral encoding protocol is proposed, based on the coherent vector states. Irreducible quantum noise-based confidentiality is achieved with only two phase values, and sixteen frequency...
