Entanglement-on-demand networks hold tremendous promise, but need heralding and storing. We report progress towards building a quantum processor using a cold rubidium ensemble in double cavity-QED system which helps herald single-photons.

The development of useful photon-photon interactions can trigger numerous breakthroughs in quantum information science, however this has remained a considerable challenge spanning several decades. Here we demonstrate the first room-temperature implem

We report the implementation of a Duan-Lukin-Cirac-Zoller (DLCZ) protocol heralded single-photon source using an ensemble of cold rubidium simultaneously coupled to two optical cavities, enabling substantial enhancements in photon generation rates.

The realization of an elementary quantum network that is intrinsically secure and operates over long distances requires the interconnection of several quantum modules performing different tasks. In this work we report the interconnection of four diff

Achieving photon-photon interactions is one of the main objectives of the quantum information technology community, since these interactions provide the basis for deterministic quantum gates with high fidelity. In the last few years new milestones in

We realize a quantum communication network combining the quantum part of the BB84 protocol with room-temperature quantum memory operation. We obtain quantum bit error rates above the classical threshold for a single-photon level operation.

Here we show an ultra-low noise regime of operation in a simple quantum memory in warm Rb atomic vapor. By modelling the quantum dynamics of four-level room temperature atoms, we achieve fidelities >90% for single-photon level polarization qubits, cl

An optical quantum memory is a stationary device that is capable of storing and recreating photonic qubits with a higher fidelity than any classical device. Thus far, these two requirements have been fulfilled for polarization qubits in systems based
