In a recent study, researchers at the University of Colorado have resolved phonon Fock states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. Fock states (or number states) are quantum states ...
A plan to develop an acoustic system to chase away seals in order to prevent shark attacks is the latest front in the debate about how Cape Cod should respond in the wake of last year's shark attacks.
