Quantum-enhanced physical-layer threat detection in metropolitan-scale fiber networks
Yung-Cheng Kao, Siddharth Pal, Alex Forencich +8
Network security is widely recognized as a key application of quantum technology. However, its large-scale deployment is hindered by the need for tight coordination between fundame…

Loss tolerant cross-Kerr enhancement via modulated squeezing
Ankit Tiwari, Daniel Burgarth, Linran Fan +2
We develop squeezing protocols to enhance cross-Kerr interactions. We show that through alternating between squeezing along different quadratures of a single photonic mode, the cro…

Superadditive Communication with the Green Machine: A Practical Demonstration of Nonlocality without Entanglement
Chaohan Cui, Jack Postlewaite, Babak N. Saif +2
Achieving the ultimate Holevo limit of optical communication capacity requires a joint-detection receiver which makes a collective quantum measurement over multiple modulated symbo…
