Metropolitan-scale heralded entanglement of solid-state qubits
Arian J. Stolk, Kian L. van der Enden, Marie-Christine Slater +20
A key challenge towards future quantum internet technology is connecting quantum processors at metropolitan scale. Here, we report on heralded entanglement between two independentl…
Deterministic creation of entangled atom-light Schrödinger-cat states
Bastian Hacker, Stephan Welte, Severin Daiss +4
Quantum physics allows for entanglement between microscopic and macroscopic objects, described by discrete and continuous variables, respectively. As in Schrödinger's famous cat ge…
Optimal storage of a single photon by a single intra-cavity atom
Luigi Giannelli, Tom Schmit, Tommaso Calarco +3
We theoretically analyse the efficiency of a quantum memory for single photons. The photons propagate along a transmission line and impinge on one of the mirrors of a high-finesse…
Increased Dimensionality of Raman Cooling in a Slightly Nonorthogonal Optical Lattice
Andreas Neuzner, Stephan Dürr, Matthias Körber +2
We experimentally study the effect of a slight nonorthogonality in a two-dimensional optical lattice onto resolved-sideband Raman cooling. We find that when the trap frequencies of…
Photon-Mediated Quantum Gate between Two Trapped Neutral Atoms in an Optical Cavity
Stephan Welte, Bastian Hacker, Severin Daiss +2
Quantum logic gates are fundamental building blocks of quantum computers. Their integration into quantum networks requires strong qubit coupling to network channels, as can be real…
Decoherence-protected memory for a single-photon qubit
M. Körber, O. Morin, S. Langenfeld +3
The long-lived, efficient storage and retrieval of a qubit encoded on a photon is an important ingredient for future quantum networks. Although systems with intrinsically long cohe…
