Simplified intensity- and phase-modulated transmitter for modulator-free decoy-state quantum key distribution
Y. S. Lo, R. I. Woodward, N. Walk +8
Quantum key distribution (QKD) allows secret key exchange between two users with unconditional security. For QKD to be widely deployed, low cost and compactness are crucial require…
Composably secure time-frequency quantum key distribution
Nathan Walk, Jonathan Barrett, Joshua Nunn
We present a composable security proof, valid against arbitrary attacks and including finite-size effects, for a high dimensional time-frequency quantum key distribution (TFQKD) pr…
Measurement-Based Noiseless Linear Amplification for Quantum Communication
Helen M. Chrzanowski, Nathan Walk, Syed M. Assad +5
Entanglement distillation is an indispensable ingredient in extended quantum communication networks. Distillation protocols are necessarily non-deterministic and require advanced e…
Quantum Key Distribution without sending a Quantum Signal
T. C. Ralph, N. Walk
Quantum Key Distribution is a quantum communication technique in which random numbers are encoded on quantum systems, usually photons, and sent from one party, Alice, to another, B…
Gaussian Post-selection for Continuous Variable Quantum Cryptography
Nathan Walk, Thomas Symul, Ping Koy Lam +1
We extend the security proof for continuous variable quantum key distribution protocols using post selection to account for arbitrary eavesdropping attacks by employing the concept…
