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

Can you see a single photon?

Can you see a single photon? We're seeking volunteers to help us find out. Read more about our single-photon vision research and fill out an interest form here.

Experiment closes the "detection loophole"

"Detection-Loophole-Free Test of Quantum Nonlocality, and Applications." DOI: 10.1103/PhysRevLett.111.130406. We used a source of entangled photons to violate a Bell inequality free of the "fair-sampling" assumption. This work was selected as an Editor's Suggestion and was featured in Physics.
