Toward quantum networking based on entanglement transfer between photons and atoms

ORAL

Abstract

Entanglement transfer is a crucial step in the realization of quantum networks. We propose to entangle atoms in separate labs by generating spectrally narrow pairs of entangled photons via cavity-enhanced spontaneous parametric downconversion and fiber-coupling them to interact with atoms in disparate experimental setups. In each lab, single-atom rotation and imaging will be employed to measure the atomic state and verify entanglement. We detail the current entangled photon setup, our scheme for atom entanglement, and progress on the cooling and site-resolved imaging in a novel experimental setup called the quantum matter synthesizer.
