Automated discovery of high-probability heralded schemes for path-entangled states
Marcello Armezzani, Colin P. Lualdi, Xuemei Gu +2
Entangled states of light lie at the heart of photonic quantum technologies, from distributed quantum communication to quantum-enhanced measurement and information processing. Thei…
Entanglement-Enhanced Quantum Nano-Vibrometry
Colin P. Lualdi, Joshua Rapp, Spencer J. Johnson +2
The study of dynamic systems at the nanometer scale can benefit from the loss and background resilience offered by quantum two-photon interference. However, fast measurements with…
Drone- and Vehicle-Based Quantum Key Distribution
Andrew Conrad, Roderick Cochran, Daniel Sanchez-Rosales +18
Quantum key distribution is a point-to-point communication protocol that leverages quantum mechanics to enable secure information exchange. Commonly, the transmitter and receiver s…
Fast quantum interferometry at the nanometer and attosecond scales with energy-entangled photons
Colin P. Lualdi, Spencer J. Johnson, Michael Vayninger +4
In classical optical interferometry, loss and background complicate achieving fast nanometer-resolution measurements with illumination at low light levels. Conversely, quantum two-…
A Quantum Key Distribution System for Mobile Platforms with Highly Indistinguishable States
Daniel Sanchez Rosales, Roderick D. Cochran, Samantha D. Isaac +2
Quantum key distribution (QKD) allows two users to exchange a provably secure key for cryptographic applications. In prepare-and-measure QKD protocols, the states must be indisting…
Public Quantum Network: The First Node
K. Kapoor, S. Hoseini, J. Choi +13
We present a quantum network that distributes entangled photons between the University of Illinois Urbana-Champaign and a public library in Urbana. The network allows members of th…
