  • When a particle crosses the event horizon of a black hole, the quantum information of the particle is quickly scrambled and entangled.
    JILA researchers have proposed a simple experiment to realize and study rapid scrambling, the process by which quantum information spreads throughout a complex system and becomes inaccessible to simple local measurements, thus becoming apparently lost. Understanding rapid scrambling, as well as how it connects to chaos and entanglement, is key not only for building quantum computers but also for explaining open question about our universe such as the behavior of black holes and quantum gravity.

    Trapping single atoms is a bit like herding cats, which makes researchers at the ¶¶Òõ´«Ã½ÔÚÏß expert feline wranglers. In a new study, a team led by physicist Cindy Regal showed that it could load groups of individual atoms into large grids with an efficiency unmatched by existing methods.
  • Using a new ultrafast electron calorimetry technique, JILA researchers in the Kapteyn-Murnane group discovered a new state in a standard material called tantalum diselenide.
    By using ultrafast lasers to measure the temperature of electrons, JILA researchers have discovered a never-before-seen state in an otherwise standard semiconductor. This research is the most recent demonstration of a new technique, called ultrafast electron calorimetry, which uses light to manipulate well-known materials in new ways.
  • Using a cantilever AFM (gray), JILA researchers are able to unfold and refold the HIV hairpin, a bend in the HIV RNA molecule which helps the virus take over the infected cell’s protein-making machinery.
    JILA researchers have demonstrated a much easier, faster and more precise way to understand the structure and function of the HIV RNA molecule, especially the HIV RNA hairpin. Furthermore, the techniques developed for this research promise to allow a wider range of users to study similar biological molecules, as they are built upon commercially available and user-friendly atomic force microscopes, or AFMs.
  • When the Ye group measured the total quantum state of buckyballs, we learned that this large molecule can play by full quantum rules. Specifically, this measurement resolved the rotational states of the buckyball, making it the largest and most complex molecule to be understood at this level.

  • Figure of trapped and cooled single alkaline-earth atoms.
    JILA researchers have, for the first time, trapped a single alkaline-earth atom and cooled it to its ground state. To trap this atom, researchers used an optical tweezer, which is a laser focused to a pinpoint that can hold, move and manipulate atoms. The full motional and electronic control wielded by this tool enables microscopically precise studies of the limiting factors in many of today’s forefront physics experiments, especially quantum information science and metrology.
  • Illustration showing rubidium and potassium atoms.
    JILA researchers have created the first quantum degenerate gas of polar molecules. This new form of matter has been a decade-long goal of molecular chemistry. This achievement will allow researchers to better understand the role of quantum physics in chemical reactions, and could make molecules a potential candidate for quantum information storage or precision measurement tools.
  • Breaking a molecular bond in CO-heme with a laser.
    The actors are molecules. The plot, broken molecular bonds. JILA Fellow Ralph Jimenez and a team of detector experts at the National Institute of Standards and Technology (NIST) are working together to make X-ray movies of a molecular drama. The team at NIST built a microcalorimeter X-ray spectrometer capable of performing time-resolved spectroscopy; in other words: a camera to film molecules. They use this camera to learn how molecules break their bonds – do the ­electrons rearrange, do the other atoms quake?
  • Figure illustrating using lasers to control chemical reactions at the quantum level.
    In the vast stretches between solar systems, heat does not flow and sound does not exist. Action seems to stop, but only if you don’t look long enough. Violent and chaotic actions occur in the long stretches of outer space. These chemical reactions between radicals and ions are the same reactions underlying the burn of a flame and floating the ozone above our planet. But they’re easy to miss in outer space because they’re very rare.
