Control Protocol for Entangled Pair Verification in Quantum Optical Networks
Vivek Vasan, Anuj Agrawal, Alexander Nico-Katz +4
We consider quantum networks, where entangled photon pairs are distributed using fibre optic links from a centralized source to entangling nodes. The entanglement is then stored (v…
Routing and Spectrum Allocation in Broadband Quantum Entanglement Distribution
Rohan Bali, Ashley N. Tittelbaugh, Shelbi L. Jenkins +5
We investigate resource allocation for quantum entanglement distribution over an optical network. We characterize and model a network architecture that employs a single broadband q…
Two-stage Quantum Estimation and the Asymptotics of Quantum-enhanced Transmittance Sensing
Zihao Gong, Boulat A. Bash
We consider estimation of a single unknown parameter embedded in a quantum state. Quantum Cramér-Rao bound (QCRB) is the ultimate limit of the mean squared error for any unbiased e…
Covert Quantum Communication Over Optical Channels
Evan J. D. Anderson, Christopher K. Eyre, Isabel M. Dailey +2
We explore covert communication of qubits over the lossy thermal-noise bosonic channel, which is a quantum-mechanical model of many practical channels, including optical. Covert co…
