Andrew Lucas (Assistant Professor, Physics), one of the winners of the early-career award, studies how quickly information spreads in quantum systems, developing new frameworks to help scientists control and send quantum information as efficiently as possible.
A new proposal from the Rey Theory Group offers hope that strontium atoms could live longer in an excited state by facilitating the creation of a dark state, which is stable and does not decay. Maintaining a long-lived excited state would open new opportunities for optical atomic clocks.
Mechanical oscillators are crucial to developing quantum computers and quantum networks, but they have to fight against noise. Measuring the quantum movement of the oscillator not only reduces its noise, it also perfectly displays the Heisenberg uncertainty principle.
The additional seed round equity financing comes from its current investors, Maverick Ventures and Global Frontier Investments, and will be used to advance the development of ColdQuanta’s cold atom Quantum Core™ technology.
O'Brian passed away unexpectedly on Thursday, November 21 at the age of 64. As a leader, O'Brian was a tireless advocate for science and its role in the community, working to engage the public and the scientific communities in this important work.
Paul Romatschke, an associate professor of physics at CU Boulder, found that when a dimension is removed from light’s space and the electron charge is turned way up, particles of light break down to half of their former selves.
In the “Pathfinding Partnerships” category, CO-LABS recognized 13 people, four of them affiliated with groups at CU Boulder: Greg Rieker, Caroline Alden, Sean Coburn, and Robert Wright. Their colleagues are from NIST and LongPath Technologies.
In the Lehnert Lab at JILA, a qubit the size of your pinky nail sits in a small copper box. Using that qubit, graduate student Lucas Sletten can measure the quietest sound in the universe: individual phonons, the smallest particles that carry sound.
Hear Professor Ana Maria Rey discuss laser cooling, quantum knots, controlling and manipulating ions, a new understanding of atomic collision, and her own groundbreaking research in the latest CU on the Air podcast.
JILA physicists and collaborators have demonstrated the first next-generation "time scale"—a system that incorporates data from multiple atomic clocks to produce a single highly accurate timekeeping signal for distribution.
