    JILA and NIST Fellow as well as University of Colorado Boulder Professor Dr. Jun Ye has been awarded a 2022 Gold Medal from the U.S. Department of Commerce (DOC). The gold medal is the highest honorary award given by the DOC and "is granted by the Secretary for distinguished performance characterized by extraordinary, notable, or prestigious contributions that impact the mission of the Department and/or one or more operating units," according to the DOC.

    JILA, NIST Fellow, and University of Colorado Boulder Professor Jun Ye has been appointed to the National Quantum Initiative Advisory Committee. In a recent announcement, President Biden聽advanced the National Quantum Initiative by appointing fifteen experts in quantum information science to the National Quantum Initiative Advisory Committee (NQIAC), with Ye being one of the members.
  • Local interactions in the same lattice pull clock frequency negative while interactions between atoms on neighboring lattice sites pull clock frequency positive. By adjusting the atomic confinement, or tightness, of the lattice, researchers can balance these two counteracting forces to increase clock sensitivity.
    Atomic clocks are essential in building a precise time standard for the world, which is a big focus for researchers at JILA. JILA and NIST Fellow Jun Ye, in particular, has studied atomic clocks for two decades, looking into ways to increase their sensitivity and accuracy. In a new paper published in Science Advances, Ye and his team collaborated with JILA and NIST Fellow Ana Maria Rey and her team to engineer a new design of clock, which demonstrated better theoretical understanding and experimental control of atomic interactions, leading to a breakthrough in the precision achievable in state-of-the-art optical atomic clocks.

    Many researchers at JILA study and use superposition and entanglement of quantum systems, including JILA fellow Adam Kaufman. Previously, Kaufman and his research team focused on improving the coherence time of the strontium atoms鈥 superposition between the ground state and the 鈥渃lock鈥 state, so named because these two states form the basis for state-of-the-art atomic clocks. As reported in two new papers, researchers from this lab have extended these studies to much larger system sizes, with an atom in a superposition of hundreds of locations, and separately, demonstrating optical clock entanglement with seconds-scale coherence time.

(A) Device cross section depicts plane waves of light that come to a focus through secondary wavelets generated by nanopillars of varying size. (B) The same metalens is used to trap and image single rubidium atoms.
    JILA Fellow Cindy Regal and her team, along with researchers at the National Institute of Standards and Technology (NIST), have for the first time demonstrated that they can trap single atoms using a novel miniaturized version of 鈥渙ptical tweezers鈥 鈥 a system that grabs atoms using a laser beam as chopsticks.

    The DoD announced today the selection of nine distinguished faculty scientists and engineers for the 2022 Class of Vannevar Bush Faculty Fellows (VBFF). This highly competitive Fellowship is named in honor of Dr. Vannevar Bush, who directed the Office of Scientific Research and Development after World War II. In line with Dr. Bush鈥檚 vision, the Fellowship aims to advance transformative, university-based fundamental research.

    鈥淭he Vannevar Bush Faculty Fellowship is the Department鈥檚 most prestigious research grant award,鈥 said Dr. Jean-Luc Cambier, the VBFF Program Director. 鈥淚t is oriented towards bold and ambitious 鈥榖lue sky鈥 research that will lead to extraordinary outcomes that may revolutionize entire disciplines, create entirely new fields, or disrupt accepted theories and perspectives.鈥 JILA and NIST Fellow Jun Ye has been distinguished as one of the 2022 Fellows.
  • JILA's custom logo commemorating its 60th anniversary
    This year, JILA celebrates its 60th anniversary. Officially established on April 13, 1962, as a joint institution between the University of Colorado Boulder and the National Institute of Standards and Technology (NIST), JILA has become a world leader in physics research. Its rich history includes three Nobel laureates, groundbreaking work in laser development, atomic clocks, underlying dedication to precision measurement, and even competitive sports leagues. The process of creating this science goliath was not always straightforward and took the dedication and hard work of many individuals.

    More than 400 years later, scientists are in the midst of an equally-important revolution. They鈥檙e diving into a previously-hidden realm鈥攆ar wilder than anything van Leeuwenhoek, known as the 鈥渇ather of microbiology,鈥 could have imagined. Some researchers, like physicists Margaret Murnane and Henry Kapteyn, are exploring this world of even tinier things with microscopes that are many times more precise than the Dutch scientist鈥檚. Others, like Jun Ye, are using lasers to cool clouds of atoms to just a millionth of a degree above absolute zero with the goal of collecting better measurements of natural phenomena.
  • The transducer developed by the Lehnert and Regal research groups uses side-banded cooling to convert microwave photons to optical photons
    The process of developing a quantum computer has seen significant progress in the past 20 years. Quantum computers are designed to solve complex problems using the intricacies of quantum mechanics. These computers can also communicate with each other by using entangled photons (photons that have connected quantum states). As a result of this entanglement, quantum communication can provide a more secure form of communication, and has been seen as a promising method for the future of a more private and faster internet.

    Qubits are a basic building block for quantum computers, but they鈥檙e also notoriously fragile鈥攖ricky to observe without erasing their information in the process. Now, new research from 蜜桃传媒破解版下载 and the National Institute of Standards and Technology (NIST) may be a leap forward for handling qubits with a light touch. In the study, a team of physicists demonstrated that it could read out the signals from a type of qubit called a superconducting qubit using laser light鈥攁nd without destroying the qubit at the same time.
