    Putting On a Particle Play

    Back in the 1950s, theoretical physicists postulated that the kinds of particles we actually see in nature are just the tip of the iceberg. Many other types of particles with weird properties, which they termed paraparticles, were popping out of the math as theoretical possibilities. But as physicists discovered more about the fundamental particles seen in nature, they found no evidence for paraparticles. In 2016 Cinthia Alderete, then a graduate student in theoretical physics, discovered a way to simulate paraparticles in which ions and light come together to put on a paraparticle play. To direct this dramatic reenactment, Alderete made the switch from theory to experiment and moved from Mexico to the United States, collaborating with the group of Norbert Linke, a member of the NSF Quantum Leap Challenge Institute for Robust Quantum Simulation and a former Fellow of the Joint Quantum Institute. Together, they brought to life an obscure theoretical curiosity from the past.

    Quantum-Safe Algorithms Face Off in NIST’s Cryptography Showdown

    While browsing the web, you might not realize that the security of your online transactions is guaranteed by a hard-to-crack math problem called factoring. But this security could evaporate in an instant—if a big enough quantum computer is built. Computers that store information in quantum hardware—like individual ions, atoms or photons—would make quick work of the factoring problem and threaten the safety of current protocols. To thwart the threat posed by possible quantum computers, the National Institute of Standards and Technology (NIST) has been running a kind of competition.

    Science in Quarantine: A Rush to Go Remote

    In this episode, we look back at the early days of the COVID-19 pandemic, when impending lab closures were threatening scientific progress and graduate student careers. We sit down with Laird Egan, then a graduate student in physics at JQI, and hear about how he and his lab mates managed to turn their ion-based quantum computer into a remote-controlled experiment in a matter of weeks. We also learn how they used their newly remote lab to achieve a milestone in quantum computing.

    Diamonds Are a Quantum Sensing Scientist’s Best Friend

    We all know that diamonds can hold great sentimental (and monetary) value. As luck may have it, diamonds—particularly defective ones, with little errors in their crystal structure—also hold great scientific value. The defects have properties that can only be described by quantum mechanics, and researchers are working on harnessing these properties to pick up on tiny signals coming from individual biological cells.

    The Secrets Atoms Hold, Part 2: Gravity

    In this episode of Relatively Certain, JQI Adjunct Fellow Marianna Safronova and JQI Fellow Charles Clark return to discuss the limits of our understanding of gravity, and how new experiments with atom interferometers may be the key to not only a higher-precision understanding of gravity but also possible new physics.

    The Secrets Atoms Hold, Part 1: Search for Dark Matter

    In this episode of Relatively Certain, Dina Genkina sits down with JQI Adjunct Fellow Marianna Safronova, a physics professor at the University of Delaware, and JQI Fellow Charles Clark, an adjunct professor of physics at UMD and a fellow of the National Institute of Standards and Technology, to talk about how precision measurements with atoms might shed some light on matter that’s otherwise dark.
