New device opens door to storing quantum information as sound waves

"flexible plates that are vibrated by sound waves at extremely high frequencies. When an electric charge is placed on those plates, they become able to interact with electrical signals carrying quantum information. This allows that information to be piped into the device for storage, and be piped out for later use—not unlike the door to the room into which you were shouting earlier in this story... based on microwaves... storage 2 orders magnitude longer"
