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.

(4) Fundamentals of Quantum Computing

  • Quantum error correction, Cluster-state model of quantum computing.
