Photonic qubits for remote quantum information processing

POSTER

Abstract

Quantum information processing between remote quantum memories relies on a fast and faithful quantum channel. Recent experiments employed both, the photonic polarization and frequency qubits, in order to entangle remote atoms [1, 2], to teleport quantum information [3] and to operate a quantum gate between distant atoms. Here, we compare the di erent schemes used in these experiments and analyze the advantages of the di erent choices of atomic and photonic qubits and their coherence properties. \\[4pt] [1] D. L.
