Quantum technologies could process information even faster if they could harness the speed of light. Using gold nanostars, the Nesbitt Lab have found a way to use light to steer electric currents, which can speed up computers and possibly enable other technologies.
Our mobile communication networks—known as multiple access channels or MACs—have a fundamental limit on how much data they can handle. Through mathematical logic games, the Graeme Smith Group found that quantum entanglement could boost that fundamental limit.
JILA Fellows Kapteyn and Murnane, whose ultrafast lasers allow scientists to view phenomena that were previously too tiny and quick-moving to observe, were recently honored with a Benjamin Franklin Medal.
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.
