Independent Rydberg atom sensing using a dual-ladder scheme https://www.sri.com/publication/quantum-pubs/independent-rydberg-atom-sensing-using-a-dual-ladder-scheme/ Thu, 02 May 2024 20:39:00 +0000 https://www.sri.com/?p=91168 SRI - A global leader in R&D with deep roots in Silicon Valley.

We show that using two independent schemes to prepare and readout the same Rydberg state can be used to perform independent measurements in general...

Closed-loop quantum interferometry for phase-resolved Rydberg-atom field sensing https://www.sri.com/publication/quantum-pubs/closed-loop-quantum-interferometry-for-phase-resolved-rydberg-atom-field-sensing/ Wed, 13 Dec 2023 15:42:54 +0000 https://www.sri.com/?p=80780 SRI - A global leader in R&D with deep roots in Silicon Valley.

In this work, we demonstrate that closed-loop quantum interferometric schemes can be used to generate a system-internal reference that can directly replace an external LO for Rydberg field sensing.
