We experimentally characterize the optical nonlinear response of a cold atomic medium placed inside an optical cavity, and excited to Rydberg states. The excitation to S and D Rydberg levels is carried out via a two-photon transition in an EIT (elect

We experimentally demonstrate, through precise characterization methods, a model of efficiently transferring a non-classical state prepared in a cold-atom memory onto a controlled light pulse, fulfilling all requirements for subsequent use in quantum

Publikováno v: 2013 IEEE Photonics Society Summer Topical Meeting Series.

A necessary part of a quantum repeater is an on-demand quantum memory. In this paper we report on recent progress of achieving such a memory in a solid-state system. We show storage of a few photon optical pulse as a spin-wave in a crystal, preservin

A long-lived solid-state quantum memory at the single photon level

Autor: Imam Usmani, Pierre Jobez, Mikael Afzelius, Nuala Timoney, Nicolas Gisin

Publikováno v: The Rochester Conferences on Coherence and Quantum Optics and the Quantum Information and Measurement meeting.

We show storage of a few photon optical pulse as a spin-wave in a crystal, preserving the states’ coherence. We show how it is possible to extend the storage time and increase the process efficiency.

We theoretically investigate the quantum statistical properties of light transmitted through an atomic medium with strong optical non-linearity induced by Rydberg-Rydberg van der Waals interactions. In our setup, atoms are located in a cavity and non
