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…
High-Speed Low-Crosstalk Detection of a Yb Qubit using Superconducting Nanowire Single Photon Detectors
Stephen Crain, Clinton Cahall, Geert Vrijsen +5
Qubits used in quantum computing tend to suffer from errors, either from the qubit interacting with the environment, or from imperfect control when quantum logic gates are applied.…
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…
Universal Model for the Turn-on Dynamics of Superconducting Nanowire Single-Photon Detectors
Kathryn L. Nicolich, Clinton Cahall, Nurul T. Islam +4
We describe an electrothermal model for the turn-on dynamics of superconducting nanowire single-photon detectors (SNSPDs). By extracting a scaling law from a well-known electrother…
Securing quantum key distribution systems using fewer states
Nurul T. Islam, Charles Ci Wen Lim, Clinton Cahall +2
Quantum key distribution (QKD) allows two remote users to establish a secret key in the presence of an eavesdropper. The users share quantum states prepared in two mutually-unbiase…
Scalable Cryogenic Read-out Circuit for a Superconducting Nanowire Single-Photon Detector System
Clinton Cahall, Daniel J. Gauthier, Jungsang Kim
The superconducting nanowire single photon detector (SNSPD) is a leading technology for quantum information science applications using photons, and they are finding increasing uses…
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…
Robust and stable delay interferometers with application to -dimensional time-frequency quantum key distribution
Nurul T. Islam, Andres Aragoneses, A. Lezama +2
We investigate experimentally a cascade of temperature-compensated unequal-path interferometers that can be used to measure frequency states in a high-dimensional quantum distribut…
