Achieving the ultimate end-to-end rates of lossy quantum communication networks
Matthew S. Winnel, Joshua J. Guanzon, Nedasadat Hosseinidehaj +1
The field of quantum communications promises the faithful distribution of quantum information, quantum entanglement, and absolutely secret keys, however, the highest rates of these…
Simple and loss-tolerant free-space QKD using a squeezed laser
Nedasadat Hosseinidehaj, Matthew S. Winnel, Timothy C. Ralph
We consider a continuous-variable (CV) quantum key distribution (QKD) protocol over free-space channels, which is simpler and more robust than typical CV QKD protocols. It uses a b…
Overcoming the repeaterless bound in continuous-variable quantum communication without quantum memories
Matthew S. Winnel, Joshua J. Guanzon, Nedasadat Hosseinidehaj +1
One of the main problems in quantum communications is how to achieve high rates at long distances. Quantum repeaters, i.e., untrusted, intermediate relay stations, are necessary to…

In Gaussian quantum key distribution eavesdropping attacks are conventionally modeled through the universal entangling cloner scheme, which is based on the premise that the whole e…
Optimal realistic attacks in continuous-variable quantum key distribution
Nedasadat Hosseinidehaj, Nathan Walk, Timothy C. Ralph
Quantum cryptographic protocols are typically analysed by assuming that potential opponents can carry out all physical operations, an assumption which grants capabilities far in ex…
