A recent study by Ana Maria Rey, James K. Thompson and their teams revealed that when measurement efficiency is greater than 19%, the quantum nondemolition (QND) measurement protocol outperformed unitary dynamical evolution—a finding with big implications for quantum metrology.
Colorado's burgeoning role in the quantum revolution was in the spotlight as U.S. Deputy Secretary of Commerce Don Graves made an official visit to CU Boulder and JILA, a joint institute of CU Boulder and the National Institute of Standards and Technology (NIST).
CU Boulder researchers, along with collaborators at Harvard University, recently observed two-axis twisting dynamics within their experimental system of ultracold potassium-rubidium molecules, which can generate entangled states for enhanced quantum sensing in the future.
"Quantum computers have the ability to break the cryptography we currently use on the internet," explains Assistant Professor Huck Bennett (Computer Science). Bennett has been funded by the NSF to investigate the feasibility of lattice-based cryptography to protect against this threat.
An international team of researchers, led by JILA and NIST Fellow Jun Ye (Physics) and his team, has made significant strides in developing a groundbreaking timekeeping device known as a nuclear clock. Their results were recently published in the cover article of Nature.
In the episode, Chancellor Justin Schwartz and Vice Chancellor for Research and Innovation Massimo Ruzzene share their vision for CUbit's role in positioning Colorado as an international quantum science and technology hub, and Executive Director Scott Sternberg offers insights into CUbit's strategic direction.
Physicists from India, Austria and the USA—including JILA Fellow Ana Maria Rey, along with NIST scientists Allison Carter and John Bollinger—have proposed a method of tweaking the electric fields that trap ions to create stable, multilayered structures, opening up exciting new possibilities for future quantum technologies.
The prestigious five-year, $1.25M grant will support Kaufman's innovative research on many-electron systems, mainly using ultracold atoms in optical lattices to simulate the Hubbard model—a fundamental framework for understanding complex phenomena like superconductivity and magnetism.
Learn how postdoctoral Research Associate Catie LeDesma and graduate student Kendall Mehling are combining machine learning with atom interferometry to create the next generation of quantum sensors, which will have major implications in disciplines as diverse as satellite navigation and measuring Earth’s composition.
CU Boulder and the College of Engineering and Applied Science are leveraging a rich legacy in quantum science and fostering a vibrant ecosystem where academic researchers, government and research laboratories and industry leaders collaborate to transform theories into real-world applications.
