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

First years win fellowships

We welcome first years Colin Lualdi and Dalton Chaffee to the group! Dalton was awarded the NASA Space Technology Research Fellowship in April 2017, which is awarded to graduate students “who show significant potential to contribute to NASA’s goal of creating innovative new space technologies.” Colin was awarded both an NSF GRFP fellowship and a College of Engineering SURGE Fellowship. Congratulations!

Quantum-memory-assisted multi-photon source

Post-doc Fumihiro Kaneda generates synchronized photons using quantum memories. Read more about this and measurement-device-independent QKD here.

Single photons and adaptive optics

Graduate student Alex Hill published work on optimization of single-mode collection on the single-photon level using a deformable mirror.
