Pushing the limits of negative group velocity
Antonius J. Renders, David Gustavsson, Marcus Lindén +4
Distortion free negative group velocity pulse propagation is demonstrated in a rare-earth-ion-doped-crystal (RE) through the creation of a carefully designed spectral absorption st…
Roadmap for Rare-earth Quantum Computing
Adam Kinos, David Hunger, Roman Kolesov +11
Several platforms are being considered as hardware for quantum technologies. For quantum computing (QC), superconducting qubits and artificially trapped ions are among the leading…
Experimental superradiance and slow light effects for quantum memories
Andreas Walther, Atia Amari, Stefan Kröll +1
The effects of high optical depth phenomena, such as superradiance, are investigated in potential quantum memory materials. The results may have relevance for several schemes, incl…
Photon-Echo Quantum Memory
W. Tittel, M. Afzelius, R. L. Cone +4
The future of long-distance quantum communication relies on the availability of quantum memory, i.e. devices that allow temporal storage of quantum information. We review research…
Backward retrieval in optical quantum memory controlled by an external field
Alexey Kalachev, Stefan Kroll
A scheme for backward retrieval in optical quantum memories in which information is stored in collective states of an extended resonant atomic ensemble is developed such that phase…
Coherent control of collective spontaneous emission in an extended atomic ensemble and quantum storage
Alexey Kalachev, Stefan Kroll
Coherent control of collective spontaneous emission in an extended atomic ensemble resonantly interacting with single-photon wave packets is analyzed. A scheme for coherent manipul…
