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!
Post-doc Fumihiro Kaneda generates synchronized photons using quantum memories. Read more about this and measurement-device-independent QKD here.
Graduate student Alex Hill published work on optimization of single-mode collection on the single-photon level using a deformable mirror.
First-year graduate student Joseph Chapman was awarded an NDSEG fellowship from the Department of Defense, and was also offered a Graduate Research Fellowship from the National Science Foundation. Congratulations!
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.

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.
Third-year graduate student Michelle Victora was selected as a 2016-2017 Mavis Future Faculty Fellow by the College of Engineering. First-year graduate student Kristina Meier was awarded an NDSEG fellowship from the Department of Defense, and was also offered a Graduate Research Fellowship from the National Science Foundation. Congratulations!
We used entangled photons to test quantum non-locality in ways that were previously beyond experimental reach, and achieved the “most nonlocal” correlations ever reported. Read more in the open-access paper: “Exploring the Limits of Quantum Nonlocality with Entangled Photons,” Bradley G. Christensen, Yeong-Cherng Liang, Nicolas Brunner, Nicolas Gisin, and Paul G. Kwiat in Physical Review X.

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:
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:
The mathematical properties of a donut (or torus) can be used to communicate quantum information more efficiently. Read more:
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.
We demonstrated a source that produces pure heralded single photons and polarization-entangled pairs without unwanted spectral correlations. Former graduate student Kevin Zielnicki is the lead author: “Engineering of near-IR photon pairs to be factorable in space-time and entangled in polarization” in Optics Express.
Second-year graduate student Alex Hill received a three-year National Defense Science & Engineering Graduate Fellowship from the Department of Defense.

“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. Read more about tests of nonlocality on our Research page.
