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 ...
