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

Take a walk through a loophole-free Bell test

Congratulations to graduate students Brad Christensen and Michael Wayne, former undergraduate Daniel Kumor, and researchers from NIST and several other institutions, who have used entangled photons in a loophole-free Bell test. We also thank graduate student Kristina Meier and undergraduates Joseph Chapman and Malhar Jere. Take a walk through the experiment in this video, and read more:

How does an optical fingerprint sensor work?

Find out how optical fingerprint sensors use total internal reflection in this video by Kwiat group members. (And vote for us in the the OSA Enabled by Optics contest before November 17!)

Graduate student Rebecca Holmes is a winner of the Emil Wolf Outstanding Student Paper Competition at FiO 2015
