Quantum repeater node with free-space coupled trapped ions
Max Bergerhoff, Omar Elshehy, Stephan Kucera +2
The quantum repeater cell is a basic building block for a quantum network, as it allows to overcome the distance limitations due to unavoidable fiber loss in direct transmission. W…
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…
Full Bell-basis measurement of an atom-photon 2-qubit state and its application for quantum networks
Elena Arenskötter, Stephan Kucera, Omar Elshehy +4
The efficiency of a Bell-state measurement on photon pairs is bound to 50\,\% due to the number of Bell states that can be distinguished using linear optics. Here we present the im…
