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…
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…
Quantum Multi-Parameter Adaptive Bayesian Estimation and Application to Super-Resolution Imaging
Kwan Kit Lee, Christos Gagatsos, Saikat Guha +1
In Bayesian estimation theory, the estimator attains the minimum mean squared error (MMSE) for estimating a scalar parameter of interest from the observatio…
