Long-lived quantum memory enabling atom-photon entanglement over 101 km telecom fiber
Yiru Zhou, Pooja Malik, Florian Fertig +6
Long-distance entanglement distribution is the key task for quantum networks, enabling applications such as secure communication and distributed quantum computing. Here we report o…
Two-stage, low noise quantum frequency conversion of single photons from silicon-vacancy centers in diamond to the telecom C-band
Marlon Schäfer, Benjamin Kambs, Dennis Herrmann +2
The silicon-vacancy center in diamond holds great promise as a qubit for quantum communication networks. However, since the optical transitions are located within the visible red s…
Calibration-Independent Certification of a Quantum Frequency Converter
Matthias Bock, Pavel Sekatski, Jean-Daniel Bancal +5
We report on a method to certify a unitary operation with the help of source and measurement apparatuses whose calibration throughout the certification process needs not be trusted…
