Mapping of a many-qubit state onto an oscillator using controlled displacements
Anders J. E. Bjerrum, Ulrik L. Andersen, Peter Rabl
We extend the controlled displacement interaction between a qubit and a harmonic oscillator to the multi-qubit (qudit) case. We define discrete quadratures of the qudit and show ho…

Long-Distance Device-Independent Conference Key Agreement
Makoto Ishihara, Anders J. E. Bjerrum, Wojciech Roga +3
Device-independent quantum key distribution (DI-QKD) enables two remote parties to share an information-theoretically secure key without any assumptions on the inner workings of th…
