Multi-mode Time-delay Interferometer for Free-space Quantum Communication
Clinton Cahall, Nurul T. Islam, Daniel J. Gauthier +1
Quantum communication schemes such as quantum key distribution (QKD) and superdense teleportation provide unique opportunities to communicate information securely. Increasingly, op…
Scalable high-rate, high-dimensional quantum key distribution
Nurul T. Islam, Charles Ci Wen Lim, Clinton Cahall +3
We propose and experimentally demonstrate a new scheme for measuring high-dimensional phase states using a two-photon interference technique, which we refer to as quantum-controlle…
Bounding the outcome of a two-photon interference measurement using weak coherent states
Andres Aragoneses, Nurul T. Islam, Michael Eggleston +3
Interference of two photons at a beamsplitter is at the core of many quantum photonic technologies, such as quantum key distribution or linear-optics quantum computing. Observing h…
Provably-Secure and High-Rate Quantum Key Distribution with Time-Bin Qudits
Nurul T. Islam, Charles Ci Wen Lim, Clinton Cahall +2
The security of conventional cryptography systems is threatened in the forthcoming era of quantum computers. Quantum key distribution (QKD) features fundamentally proven security a…
