Quantum Photonic Applications Group

The core focus of the Quantum Photonic Applications group lies in investigating mathematical foundations, application development, and experimental system design for quantum-enhanced and/or quantum-enabled photonic information processing. This includes all applications where light is used to extract, carry and process information, e.g., in communications, sensing, imaging, and various special-purpose computations. Calculating the fundamental performance limits in the aforesaid applications must treat light as a quantum mechanical object. Designing, evaluating and building systems that attain or approach such quantum-limited performance, often involves innovations spanning multiple disciplines.

Our research employs a confluence of: (1) optical physics (electromagnetic theory, statistical optics, non-linear optics, and quantum optics), (2) information and estimation theories (Shannon theory, quantum information theory, quantum Fisher information, network information theory), (3) communications and networking systems (digital communications, network algorithms, quantum repeaters, quantum communications systems), and (4) fundamentals of quantum computing (e.g., quantum error correction, cluster-state model of quantum computing).
