News and Events

New QIS group member: Nicholas Peters joined the QIS group on January 20, 2015. Nick earned a Ph.D. in Physics from the University of Illinois and has spent the past several years studying quantum communication in the telecommunications industry. Welcome to ORNL, Nick!


Congratulations to Brian Williams, who successfully defended his PhD thesis, “Nonlocal Polarization Interferometry and Entanglement Detection,” at the University of Tennessee on November 7, 2014. Great job Dr. Williams! And a subsequent "Welcome to ORNL!" Brian joined the QIS group as a postdoc in December, 2014.

QIS researchers have been awarded a grant from the Cybersecurity for Energy Delivery Systems (CEDS) program in DOE’s Office of Electricity. The three-year project, which is entitled “Timing Authentication Secured by Quantum Correlations,” will combine quantum key distribution techniques with wireless communication to provide timing signals that are not subject to GPS spoofing. The project will be led by Phil Evans, and includes partners from PNNL, Sandia NL, Qubittek, Pacific Gas & Electric, and the University of Texas at Austin.

New LDRDs: QIS researchers have been awarded FOUR new ORNL LDRD projects:

"Quantum key distribution through existing optical fiber networks using untrusted devices,” Bing Qi
"Quantum-enhanced plasmonic ultra-trace sensors,” Raphael Pooser
"Phase change material detectors for single photon detection in the UV-Vis region,” Phil Evans
“Nonlinear nanophotonics with ultrastrong plasmonic coupling,” Ben Lawrie

We are looking forward to contributing to the ORNL mission through these innovative, cutting-edge research projects.

Raphael Pooser, along with Alberto Marino at the University of Oklahoma, have been awarded a grant from the William and Mary Keck Foundation. The proposal builds off of quantum plasmonics capabilities developed at ORNL by Pooser and Ben Lawrie. The goal of the four-year project is to develop a sensor that can detect low concentrations of biological agents, such as circulating tumor cells in blood, using state of the art plasmonic devices and quantum noise reduction.
