Generation of large-amplitude squeezed cat states with near-unity efficiency
Simon K. Yung, Matthew S. Winnel, Timothy C. Ralph +1
The Gottesman-Kitaev-Preskill encoding has emerged as a leading candidate for fault-tolerant quantum computation with continuous variables. For photonic architectures, the major ch…
All-photonic quantum key distribution beyond the single-repeater bound
Matthew S. Winnel, Sergio Juárez, Chithrabhanu Perumangatt +2
Quantum protocols require classical signaling, and when classical signals propagate faster than quantum ones, standard rate-loss limits can be surpassed. We introduce an all-photon…
Gaussian Atemporality: When Gaussian Quantum Correlations Imply Common Cause
Minjeong Song, Jayne Thompson, Matthew S. Winnel +4
Conventionally, covariances do not distinguish between spatial and temporal correlations. The same covariance matrix could equally describe temporal correlations between observatio…

Petros Laccotripes, Junyang Huang, Ginny Shooter +6
Multiphoton entangled states are a key resource for quantum networks and measurement-based quantum computation. Scalable protocols for generating such states using solid-state spin…
A heralded quantum amplifier of multi-photon states
Luis Villegas-Aguilar, Farzad Ghafari, Matthew S. Winnel +5
Large-scale quantum networking systems will inevitably require methods to overcome photon loss. While the no-cloning theorem forbids perfect and deterministic amplification of unkn…

Quantum communications harness quantum phenomena like superposition and entanglement to enhance information transfer between remote nodes. Coherent quantum communications, essentia…
Classical-Quantum Dual Encoding for Laser Communications in Space
Matthew S. Winnel, Ziqing Wang, Robert Malaney +3
In typical laser communications classical information is encoded by modulating the amplitude of the laser beam and measured via direct detection. We add a layer of security using q…
