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

Physics-based escape room open in Urbana

Professor S. has gone missing. Four government agents have disappeared. Can you solve the mystery, save the free world, and maybe learn something too? The world’s first science-based escape room is now open in Urbana, IL, a physics outreach project developed by Professor Paul Kwiat with support from the American Physical Society and Physics Illinois.

Students win OSA Enabled by Optics contest with video about fingerprint sensors

Graduate students Courtney Krafczyk, Rebecca Holmes, Michelle Victora and JJ Wong, and undergraduate Sheldon Schlie were the winners of the OSA Enabled by Optics contest with their video about the optics of fingerprint sensors! The video explains total internal reflection and other optics concepts with cartoons and demonstrations.
