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…
CV-MDI-QKD: One-mode Gaussian attacks are not enough
Carlo Ottaviani, Gaetana Spedalieri, Samuel L. Braunstein +1
The security proof of continuous variable (CV) measurement device independent (MDI) quantum key distribution (QKD) cannot be reduced to the analysis of one-mode Gaussian attacks (i…
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-…
Quantum fidelity for arbitrary Gaussian states
Leonardo Banchi, Samuel L. Braunstein, Stefano Pirandola
We derive a computable analytical formula for the quantum fidelity between two arbitrary multimode Gaussian states which is simply expressed in terms of their first- and second-ord…
Continuous-variable quantum cryptography with an untrusted relay: Detailed security analysis of the symmetric configuration
Carlo Ottaviani, Gaetana Spedalieri, Samuel L. Braunstein +1
We consider the continuous-variable protocol of Pirandola et al. [Nature Photonics 9, 397-402 (2015), see also arXiv.1312.4104] where the secret-key is established by the measureme…
Advances in Quantum Teleportation
Stefano Pirandola, Jens Eisert, Christian Weedbrook +2
Quantum teleportation is one of the most important protocols in quantum information. By exploiting the physical resource of entanglement, quantum teleportation serves as a key prim…
