Experiment takes “snapshots” of light, stops light, and uses light to change properties of matter

Light travels at a speed of about 300,000,000 meters per second as light particles, photons, or equivalently as electromagnetic field waves. Experiments led by Hrvoje Petek examined ideas surrounding the origins of light, taking snapshots of light, stopping light and using it to change properties of matter.

Petek worked with student Yannan Dai and collaborators Prof. Chen-Bin (Robin) Huang of the National Tsing Hua University in Taiwan, and Atsushi Kubo of the Tsukuba University of Japan on the experiments. Their findings were reported in the paper, “Plasmonic topological quasiparticle on the nanometre and femtosecond scales,” which was published in the Dec. 24 issue of Nature magazine.

Prof. Lillian Chong and graduate student, Anthony Bogetti, were part of a multi-institution team effort that won the Association for Computing Machinery’s Gordon Bell Special Prize for High Performance Computing-Based COVID-19 Research, commonly referred to as the Nobel Prize of Supercomputing. A crowning achievement of this effort is the generation of atomically detailed views of how the spike protein of the coronavirus opens up before latching onto cells during infection.

​​​​​​​Mechanical engineering professors Hessam Babaee and Peyman Givi recently received an award from the National Science Foundation (NSF) for a three-year project titled “Real-Time and Adaptive Chemical Kinetic Model Reduction Coupled with Turbulence.” 

The chemistry of combustion involves understanding how a large number of species behave and evolve in a given operating condition.  The tractability of this technically important problem becomes increasingly difficult when the operation involves turbulent mixing.

The Quantum2020 Spooky Action at a Distance poster session was held remotely over multiple Zoom sessions on October 29th, 2020. We had a team of 20 judges coming from various departments at Pitt, CMU, and Duquesne comprising both faculty members, postdocs and previous poster award winners, who evaluated the poster presentations of 44 participants hailing from physics, engineering, chemistry, and other disciplines. 

The full video playlist is linked here, and the descriptions of each video contain quicklinks to the beginning of each presentation. Thank you to everyone who participated!

The six presenters that received the highest overall scores are:

We invite the PQI community to attend Quantum2020 “Spooky Action at a Distance - a Remote Poster Session”  that takes place October 29th, 2020 from 3-5:15 PM over 2 sessions (Session A 3PM-4PM, Session B 4:15PM-5:15PM). View the poster gallery and schedule at!

This is an interdisciplinary event with a focus on quantum science and engineering! We are encouraging the participants to make their presentation accessible to a broad audience to foster potential collaborations and lessen communication barriers that may exist between different fields.

Facebook and Carnegie Mellon Launch the Open Catalyst Project

Facebook AI and Professor Zach Ulissi in the Carnegie Mellon University (CMU) Department of Chemical Engineering are announcing the Open Catalyst Project, a collaboration intended to use AI to accelerate quantum mechanical simulations by 1,000x in order to discover new electrocatalysts needed for more efficient and scalable ways to store and use renewable energy. The overview paper and dataset paper for this work can be found on

Wind and solar energy are vital parts of the modern energy grid, especially if we hope to combat climate change. Unfortunately, the sun doesn’t always shine and the wind doesn’t always blow. Both provide intermittent power, with California, for instance, seeing peak solar generation in the afternoon rather than in the evening, when demand spikes. Increasing our reliance on renewable energy requires storing power for days, weeks, or even months so that it’s available when needed.

Brookhaven National Laboratory was selected by the U.S. Department of Energy (DOE) Office of Science to lead one of the five National Quantum Information Science (QIS) Research Centers. Brookhaven Lab will lead the Co-design Center for Quantum Advantage (C2QA), which will focus on quantum computing.

Over the next five years, C2QA will be awarded up to $115 million to build the fundamental tools necessary for the United States to create scalable, distributed, and fault-tolerant quantum computer systems.  The C2QA team comprises several national labs, research centers, universities, and industry. Among their collaborators, Brookhaven has partnered with Prof. Michael Hatridge at the University of Pittsburgh.

Musings on the U.S Quantum Economy

The Quantum Information Science and Technology (QIST) Summit, hosted by the Department of Energy's Brookhaven National Lab, took place on October 7-8th and connected industry, governmental, and academic experts to discuss six broad themes in panel sessions. PQI students attended the online event and prepared summaries of each panel.

The first of the panels was titled “Considerations for Building the US Quantum Economy”. The panelists covered topics like ethical considerations, industrial impacts, and market opportunities for the future of quantum in the economy. The moderator was Rima Kasia Oueid, the Commercialization Executive of the Office of Technology Transitions at the Department of Energy
