Agile and versatile quantum communication: signatures and secrets
Stefan Richter, Matthew Thornton, Imran Khan +7
Agile cryptography allows for a resource-efficient swap of a cryptographic core in case the security of an underlying classical cryptographic algorithm becomes compromised. Convers…
Squeezed vacuum states from a whispering gallery mode resonator
Alexander Otterpohl, Florian Sedlmeir, Ulrich Vogl +9
Squeezed vacuum states enable optical measurements below the quantum limit and hence are a valuable resource for applications in quantum metrology and also quantum communication. H…
Characterizing micro-macro transitions with an atomic-vapor-based linear optical amplifier
Zhifan Zhou, Ulrich Vogl, Ryan T. Glasser +4
Fundamentally, the dynamics of micro-macro transitions is instrumental to understanding the process of quantum-to-classical transitions; technologically, it can also facilitate the…
Efficient single sideband microwave to optical conversion using an electro-optical whispering gallery mode resonator
Alfredo Rueda, Florian Sedlmeir, Michele C. Collodo +9
Linking classical microwave electrical circuits to the optical telecommunication band is at the core of modern communication. Future quantum information networks will require coher…
Frequency tuning of a triply-resonant whispering-gallery mode resonator to MHz wide transitions for proposed quantum repeater schemes
Gerhard Schunk, Ulrich Vogl, Florian Sedlmeir +6
Quantum repeaters rely on an interfacing of flying qubits with quantum memories. The most common implementations include a narrowband single photon matched in bandwidth and central…
Interfacing transitions of different alkali atoms and telecom bands using one narrowband photon pair source
Gerhard Schunk, Ulrich Vogl, Dmitry V. Strekalov +7
Quantum information technology strongly relies on coupling of optical photons with narrowband quantum systems, such as quantum dots, color centers, and atomic systems. This couplin…
