A bit of a ‘quantum magic trick’
Is there a faster way to determine a frequency? It turns out there is, in a new discovery published this week in Physical Review Letters by a collaboration between a Washington University in St. Louis and the University of Rochester.
Shaking Schrödinger’s cat
Frequent measurement of a quantum system’s state can either speed or delay its collapse, effects called the quantum Zeno and quantum anti-Zeno effect. But so too can “quasimeasurements” that only poke the system and garner no information about its state.
Murch wins Sloan Research Fellowship
The Alfred P. Sloan Foundation announced Feb. 23 that Kater Murch, PhD, assistant professor of physics in Arts & Sciences at Washington University in St. Louis, has been awarded a 2015 Sloan Research Fellowship. He is among 126 outstanding U.S. and Canadian researchers selected as fellowship recipients this year. The fellowships are given to early-career scientists and scholars whose achievements and potential identify them as rising stars, the next generation of scientific leaders.
