Building the Frequency and Time Backbone for Quantum Technologies

Quantum computing, optical clocks, and quantum communication increasingly depend on a common enabling infrastructure: reliable and low-noise frequency & time (F&T) distribution. As quantum technologies move from laboratory experiments toward larger, networked, and deployable systems, these F&T systems must deliver the same frequency stability and timing precision at larger scales and under real-world environmental conditions.

This talk will introduce key technologies to address this challenge. Stabilized fiber-optic links allow the transfer of either RF or optical reference F&T signals from campus-scale installations to distances of tens of kilometers without compromising their performance. Ultra-low-noise atomic clocks and femtosecond laser oscillators as well as high-precision monitoring, comparison, and distribution electronics allow to build up complete and robust architectures. Together, these solutions provide the backbone needed to scale the deployment and interconnection of optical clocks, modular quantum computers, and quantum key distribution networks.
