Weight Hybrid Architecture of Rydberg-Atomic Sensors

Chen Gong, Hao Wu, Kaibin Huang, Rui Ni, Shanchi Wu, Xinyuan Yao

A four-channel weight hybrid architecture combines dual signal and dual noise channels via maximum likelihood estimation to reduce laser-induced noise in Rydberg atomic sensors.

Claims

C1strongest claim

By jointly processing dual signal channels and dual noise reference channels, the WH architecture effectively mitigates noise contributions from lasers and other hardware components. All channels are optimally combined via maximum likelihood estimation within an expectation maximization framework, enabling robust signal extraction under correlated noise.

C2weakest assumption

That the laser and hardware noise is sufficiently correlated across the four channels for the maximum-likelihood combiner inside the expectation-maximization framework to produce a meaningful improvement over conventional single-channel or two-channel processing.

C3one line summary

A four-channel weight hybrid scheme using maximum likelihood estimation within an expectation maximization framework mitigates correlated laser and hardware noise in Rydberg atomic quantum receivers.
