Telecom Quantum Photonic Interface for a Ca Single-Ion Quantum Memory
Elena Arenskötter, Tobias Bauer, Stephan Kucera +3
Entanglement-based quantum networks require quantum photonic interfaces between stationary quantum memories and photons, enabling entanglement distribution. Here we present such a…
Extending Quantum Links: Modules for Fiber- and Memory-Based Quantum Repeaters
Peter van Loock, Wolfgang Alt, Christoph Becher +9
We analyze elementary building blocks for quantum repeaters based on fiber channels and memory stations. Implementations are considered for three different physical platforms, for…
Optical bistability and nonlinear dynamics by saturation of cold Yb atoms in a cavity
Hannes Gothe, Tristan Valenzuela, Matteo Cristiani +1
We observed optical bistability as well as oscillations in the upper bistable branch when cold ytterbium atoms are dispersively coupled to a high finesse optical cavity. Comparable…
Continuous-wave virtual-state lasing from cold ytterbium atoms
Hannes Gothe, Dmitriy Sholokhov, Anna Breunig +2
While conventional lasers are based on gain media with three or four real levels, unconventional lasers including virtual levels and two-photon processes offer new opportunities. W…
High-fidelity entanglement between a trapped ion and a telecom photon via quantum frequency conversion
Matthias Bock, Pascal Eich, Stephan Kucera +4
Entanglement between a stationary quantum system and a flying qubit is an essential ingredient of a quantum-repeater network. It has been demonstrated for trapped ions, trapped ato…
Coherence and Entanglement Preservation of Frequency-Converted Heralded Single Photons
Andreas Lenhard, José Brito, Matthias Bock +2
We report on quantum frequency conversion of near-infrared photons from a wavelength of 854nm to the telecommunication O-band at 1310nm with 8% overall conversion efficiency. Entan…
