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…
Channel purification via continuous-variable quantum teleportation with Gaussian post-selection
Rémi Blandino, Nathan Walk, Austin P. Lund +1
We present a protocol based on continuous-variable quantum teleportation and Gaussian post- selection that can be used to correct errors introduced by a lossy channel. We first sho…
Experimental demonstration of Gaussian protocols for one-sided device-independent quantum key distribution
Nathan Walk, Sara Hosseni, Jiao Geng +9
Nonlocal correlations, a longstanding foundational topic in quantum information, have recently found application as a resource for cryptographic tasks where not all devices are tru…
