Welcome to the

Kwiat Quantum Information Group

in the Department of Physics in Engineering & LAS at Illinois

About us

We are a quantum information research group in the physics department at the University of Illinois at Urbana-Champaign.

Our research interests include:

  • Fundamental studies of quantum mechanics
  • Optical quantum information resources including single-photon sources, single-photon detectors, sources of entanglement, quantum random number generators, and adaptive optics
  • Applications such as quantum key distribution, quantum state and process tomography, quantum state creation and remote preparation, hyperentanglement-enhanced quantum communication, quantum-enhanced precision measurements, and quantum memory
  • The interaction of quantum states of light with biological systems, including the human visual system
