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…
Zero-added-loss entanglement multiplexing using time-bin spectral shearing
Joseph C. Chapman, Muneer Alshowkan, Jack Postlewaite +2
High-quality quantum communications that enable important capabilities, such as distributed quantum computing and sensing, will require quantum repeaters for providing high-quality…
Hardware-Efficient Universal Linear Transformations for Optical Modes in the Synthetic Time Dimension
Jasvith Raj Basani, Chaohan Cui, Jack Postlewaite +2
Recent progress in photonic information processing has spurred strong demand in scalable and reconfigurable photonic circuitry. Conventional spatially-meshed multi-port interferome…
Programmable pixel-mode linear interferometers using multi-plane light conversion
Mushkan Sureka, Itay Ozer, Wenhua He +3
Programmable linear optical interferometers are a core primitive in optical signal processing, quantum information processing, and photonic computing. Existing photonic-integrated…
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…
