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

Studying the visual system with single photons

Physics and psychology unite! We're using quantum optics to find out whether humans can see a single photon (and maybe even its superposition). Read more:

Happy National Donut Day!

The mathematical properties of a donut (or torus) can be used to communicate quantum information more efficiently. Read more:

Superdense teleportation using hyperentangled photons

We demonstrated a superdense teleportation protocol for higher-fidelity transmission of quantum information with fewer experimental resources: "Superdense teleportation of quantum information," Trent Graham et al. in Nature Communications. Read more on the Physics Illinois website.
