Performance of Quantum Preprocessing under Phase Noise
Zuhra Amiri, Boulat A. Bash, Janis Nötzel
Optical fiber transmission systems form the backbone of today's communication networks and will be of high importance for future networks as well. Among the prominent noise effects…
Transceiver designs to attain the entanglement assisted communications capacity
Ali Cox, Quntao Zhuang, Christos Gagatsos +2
Pre-shared entanglement can significantly boost communication rates in the high thermal noise and low-brightness transmitter regime. In this regime, for a lossy-bosonic channel wit…
Quantum-Enhanced Transmittance Sensing
Zihao Gong, Nathaniel Rodriguez, Christos N. Gagatsos +2
We consider the problem of estimating unknown transmittance of a target bathed in thermal background light. As quantum estimation theory yields the fundamental limits, we emplo…
Fundamental Limits of Thermal-noise Lossy Bosonic Multiple Access Channel
Evan J. D. Anderson, Boulat A. Bash
Bosonic channels describe quantum-mechanically many practical communication links such as optical, microwave, and radiofrequency. We investigate the maximum rates for the bosonic m…
Demonstration of Entanglement-Enhanced Covert Sensing
Shuhong Hao, Haowei Shi, Christos N. Gagatsos +6
The laws of quantum physics endow superior performance and security for information processing: quantum sensing harnesses nonclassical resources to enable measurement precision unm…
