Boulder, Colo. 鈥 Physicist Adam Kaufman of both JILA and the U.S. Department of Commerce鈥檚 National Institute of Standards and Technology (NIST) has been awarded the聽2023 New Horizons in Physics Prize聽from the Breakthrough Prize Foundation for his work in advancing the control of atoms and molecules to improve atomic clocks and quantum information processing.
In a new paper published in PRX Quantum, Rey and her team of researchers proposed a new method for seeing the quantum effects enabled by SU(n) symmetry in current experimental conditions, something that has been historically challenging for physicists.
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.
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.
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 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.
University of Colorado President Todd Saliman visited JILA this past week and toured the laboratories at the invitation of JILA and NIST Fellow Eric Cornell. Saliman was impressed by the research team and Fellows and applauded their work. 鈥淵ou are all working to change the world,鈥 President Saliman said.
