Sound can be just as quantum as light. But our toolbox for single quanta of sound, i.e. phonons, is currently insufficient. Here we describe a new component that enables a chip-based, solid-state analogue of cavity-QED utilizing acoustic phonons instead of photons, phonitons instead of polaritons. We show how long-lived and tunable acceptor (hole) impurity states […]

Could the Next World-Changing Technology Emerge From UMD? (Not exactly how we would hype it, but we appreciate the support!) Phonitons as a Sound-based Analogue of Cavity Quantum Electrodynamics Charles George Tahan, Rousko Todorov Hristov, Oney O. Soykal Researchers at the University of Maryland and the National Security Agency (NSA) have developed the analog of […]

“Phononiton” has become “phoniton” by negotiation with the editors of PRL. It’s etymologically cleaner. The good news is that our paper has been accepted for publication in PRL and the new term “phoniton” has been accepted as well. See our summary for more information.

The progression of quantum technology relies in part on the identification and control of components, such as confined electrons or photons, from which systems of greater complexity are built. Here we describe another potentially valuable component, a composite object formed as a quantum mechanical superposition of a long-lived, localized phonon and a matter excitation: half-sound, half-matter.

In 2005 we predicted “quantum phase transitions of light.” It seemed crazy at the time. Check out number 6: Physics World reveals its top 10 breakthroughs for 2010.

Goodbye to Leslie Ross, who returns to the University of Illinois, Urbana-Champaign, to continue her pursuit of a PhD in condensed matter theory. Leslie spent the summer here as part of an NPSC Graduate Fellowship doing important research on the memory error rates of silicon qubits in quantum computers. Good luck to her, a truly […]
