Two (Photons) is Company, Three’s a Crowd
Photons—the quantum particles of light—normally don’t have any sense of personal space. A laser crams tons of photons into a tight beam, and they couldn’t care less that they are packed on top of each other. Two beams can even pass through each other without noticing. This is all well and good when making an extravagant laser light show or using a laser level to hang a picture frame straight, but for researchers looking to develop quantum technologies that require precise control over just one or two photons, this lack of interaction often makes life difficult. Now, a group of UMD researchers has come together to create tailored interactions between photons in an experiment where, at least for photons, two’s company but three’s a crowd. The technique builds on many previous experiments that use atoms as intermediaries to form connections between photons that are akin to the bonds between protons, electrons and other kinds of matter. These interactions, along with the ability to control them, promises new opportunities for researchers to study the physics of exotic interactions and develop light-based quantum technologies.
JQI Fellow Gorshkov to Receive Flemming Award for Outstanding Federal Service
Alexey Gorshkov, a physicist at the National Institute of Standards and Technology (NIST) and a Fellow of the Joint Quantum Institute (JQI) and the Joint Center for Quantum Information and Computer Science (QuICS), is among 12 exceptional public servants chosen to receive the Arthur S. Flemming Award for 2020. The awardees will be honored during a virtual celebration this summer.
Gorshkov Summer Student Named Regeneron Science Talent Search Finalist
Timothy Qian, a senior at Montgomery Blair High School, has been named a finalist in the Regeneron Science Talent Search (STS) 2021 competition for the research from his summer research internship at the University of Maryland. He performed the work with the mentorship of JQI Fellow Alexey Gorshkov, who is also a physicist at the National Institute of Standards and Technology and a Fellow of the Joint Center for Quantum Information and Computer Science, and Jacob Bringewatt, a graduate student in physics at UMD. He developed a procedure for using networks of quantum sensors to perform optimal measurements of things like the electric field generated at a particular point by a distribution of electrons or the magnetic field produced by atomic nuclei.
