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 ...
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 ...

Quantum information platforms are based on qubits that talk to each other and photons (optical and microwave) are the carrier of choice—to date, to transfer quantum states between qubits. However, in some solid-state systems, ...
Acoustic tweezers are based on focused acoustic vortices and hold promise to precisely manipulate microorganisms and cells from the millimeter scale down to the submicron scale, without contact, and with unprecedented selectivity ...
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 ...

Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses. These structures can control ...
Motivated by a desire to help find Malaysia Airlines flight MH370, which is believed to have crashed into the southern Indian Ocean in March 2014, we proposed a way of working out where objects hit the surface of the ocean ...
