Event Details & Abstracts

I will provide an overview of two foundational research projects underway at the Army Research Lab.  1: Rydberg atoms can exhibit the largest electro-optic effect of any material.  This opens a Pandora's box of radio frequency (RF) applications based on Rydberg atom quantum sensors.  What are the strengths and weaknesses of quantum sensors compared to traditional RF tech?   2:  Atoms in cavities are great light-qubit interfaces, but scaling up to hundreds or thousands of qubits is a real challenge.  I will discuss our development and recent demonstrations in an atom-cavity system with holographic multiplexing that may allow independent cavity control and dynamic interactions of up to 1000 qubits.
