Artificial materials reconstruct porpoise's echolocation

Over millions of years, porpoises have developed powerful biosonar with high accuracy and intelligence to detect and track prey in noisy underwater environments. The sound source in a porpoise is about one half of the wavelength ...

Coupling qubits to sound in a multimode cavity

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 ...

Locating a shooter from the first shot via cellphone

In the past several decades, militaries have worked hard to develop technologies that simultaneously protect infantry soldiers' hearing and aid in battlefield communication. However, these advanced Tactical Communication ...

It's a one-way street for sound waves in this new technology

Imagine being able to hear people whispering in the next room, while the raucous party in your own room is inaudible to the whisperers. Yale researchers have found a way to do just that—make sound flow in one direction—within ...
