Professor Scott Diddams (Electrical Engineering, Physics) was elected for his contributions to optical frequency combs and their applications. Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer.
After graduation, Wu joined Quantinuum, where her extensive background in ion trapping is well applied in helping Quantinuum develop ion-trap-based quantum technologies. “I’m excited to be part of this journey and to help build extremely advanced quantum computers for the future," Wu says.
“The Frequency comb laser was originally invented for optical atomic clocks, but very early on, we identified its powerful application for molecular sensing,” said Jun Ye, a fellow of JILA and NIST and professor adjoint of physics at CU Boulder. “Still, it took us 20 years to mature this technique, finally allowing universal applicability for molecular sensing.”
When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their nuclei—has a lot to say about how they bounce off each other. This is especially true for atoms cooled to near-zero Kelvin, where quantum mechanical effects give rise to unexpected phenomena.
As the snow fell the last weekend in January, 180 undergraduate students gathered in the Duane Physics building at the University of Colorado Boulder for the Conference for Undergraduate Women and Gender Minorities in Physics (CU*iP), an annual three-day event sponsored by the American Physical Society.
Understanding whether and why many-body localization (MBL) happens can help scientists delve into the fundamental laws of nature and unlock new possibilities for technologies like quantum computing, where preventing the loss of quantum information is critical.
A team of physicists and engineers at the CU Boulder has discovered a new way to measure the orientation of magnetic fields using what may be the tiniest compasses around—atoms. The group’s findings could one day lead to a host of new quantum sensors.
JILA and NIST Fellows Ana Maria Rey and James K. Thompson, along with researchers from the University of Strasbourg, have published a study in Physical Review Letters that could open new avenues in quantum information science and quantum computing, offering a potential path for the development of highly entangled and scalable quantum systems.
For the first time ever, scientists have used a technique called “quantum squeezing” to improve the gas sensing performance of optical frequency comb lasers, which scientists use to spot methane leaks in the air above oil and gas operations and signs of COVID-19 infections in breath samples from humans.
To kick off the International Year of Quantum Science and Technology in 2025, three Colorado universities in collaboration with Elevate Quantum have announced that a new facility for fostering quantum technologies is coming to Colorado.
