Quantum cryptography with an ideal local relay
Gaetana Spedalieri, Carlo Ottaviani, Samuel L. Braunstein +4
We consider two remote parties connected to a relay by two quantum channels. To generate a secret key, they transmit coherent states to the relay, where the states are subject to a…
MDI-QKD: Continuous- versus discrete-variables at metropolitan distances
Stefano Pirandola, Carlo Ottaviani, Gaetana Spedalieri +6
In a comment, Xu, Curty, Qi, Qian, and Lo claimed that discrete-variable (DV) measurement device independent (MDI) quantum key distribution (QKD) would compete with its continuous-…
Continuous Variable Quantum Key Distribution with a Noisy Laser
Christian S. Jacobsen, Tobias Gehring, Ulrik L. Andersen
Existing experimental implementations of continuous-variable quantum key distribution require shot-noise limited operation, achieved with shot-noise limited lasers. However, loosen…
Single-Quadrature Continuous-Variable Quantum Key Distribution
Tobias Gehring, Christian S. Jacobsen, Ulrik L. Andersen
Most continuous-variable quantum key distribution schemes are based on the Gaussian modulation of coherent states followed by continuous quadrature detection using homodyne detecto…
Non-Markovian Reactivation of Quantum Relays
Stefano Pirandola, Carlo Ottaviani, Christian S. Jacobsen +4
We consider a quantum relay which is used by two parties to perform several continuous-variable protocols: Entanglement swapping, distillation, quantum teleportation, and quantum k…
