Project Description:

Scalable quantum interaction of flying qubits (photons) with stationary qubits (e.g. atoms) has broad applications ranging from sensing to communication and computation. Using novel material and nanofabrication techniques we engineer light-atom interaction Hamiltonian in chip-scale photonic devices. We aim to discover new interaction regimes with reduced loss and enhanced nonlinearity addressing some of the main challenges of a future quantum internet. We aim to develop high purity material, perform nanofabrication processes, and characterize quantum optical properties of rare-earth crystalline materials to develop quantum optical memories and sources. To increase the coherence time of atoms storing quantum information, we develop high-purity materials with integration ability with a photonic chip. To enhance interaction strength and reduce losses, we rely on engineering periodic arrays of atoms in a nanophotonic cavity and we leverage both atomic and optical resonances to enhance nonlinearity and reduce spontaneous emission noise. System-level integration of rare-earth photonic memories with entangled quantum sources for advancing quantum networking is the overarching goal of this project.
