Deterministic Single-Photon Source for Distributed Quantum Networking
Axel Kuhn, Markus Hennrich, Gerhard Rempe
A sequence of single photons is emitted on demand from a single three-level atom strongly coupled to a high-finesse optical cavity. The photons are generated by an adiabatically dr…
Feshbach Spectroscopy of a Shape Resonance
Thomas Volz, Stephan Dürr, Niels Syassen +3
We present a new spectroscopy technique for studying cold-collision properties. The technique is based on the association and dissociation of ultracold molecules using a magnetical…
Two-cavity-mediated photon-pair emission by one atom
Gianvito Chiarella, Tobias Frank, Pau Farrera +1
Photon-pair sources are widely used in quantum optics and quantum information experiments. Despite their broad deployment, there has not yet been an on-demand implementation with e…
A Single-Photon Server with Just One Atom
Markus Hijlkema, Bernhard Weber, Holger P. Specht +3
Neutral atoms are ideal objects for the deterministic processing of quantum information. Entanglement operations have been performed by photon exchange or controlled collisions. At…
Ground-State Cooling of a Single Atom at the Center of an Optical Cavity
Andreas Reiserer, Christian Nölleke, Stephan Ritter +1
A single neutral atom is trapped in a three-dimensional optical lattice at the center of a high-finesse optical resonator. Using fluorescence imaging and a shiftable standing-wave…
Quantum-Logic Gate between Two Optical Photons with an Average Efficiency above 40%
Thomas Stolz, Hendrik Hegels, Maximilian Winter +5
Optical qubits uniquely combine information transfer in optical fibers with a good processing capability and are therefore attractive tools for quantum technologies. A large challe…
