Metropolitan entanglement distribution between an atom and a near-visible photon
Maya Büki, Pooja Malik, Florian Fertig +9
Entanglement distribution is the overarching purpose of quantum networks. While communication over long distances can use deployed fiber infrastructure, it requires photons in the…
Efficient entanglement of three remote single-atom quantum-network nodes
Matthias Seubert, Leonardo Ruscio, Tobias Frank +6
Entanglement distributed over a set of individually addressable qubit nodes is the enabling resource for a plethora of applications ranging from tests of quantum physics to secure…
A source of heralded atom-photon entanglement for quantum networking
Gianvito Chiarella, Tobias Frank, Leart Zuka +2
Communication in quantum networks suffers notoriously from photon loss. Resulting errors can be mitigated with a suitable measurement herald at the receiving node. However, waiting…
Tweezer-assisted subwavelength positioning of atomic arrays in an optical cavity
Matthias Seubert, Lukas Hartung, Stephan Welte +2
We present an experimental technique that enables the preparation of defect-free arrays of 87Rb atoms within a microscopic high-finesse optical standing-wave cavity. By employing o…
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…
