Storing Quantum Information as Sound Waves with New Device.

Mohammad Mirhosseini, assistant professor of electrical engineering and applied physics, has developed a new method for efficiently translating electrical quantum states into sound and vice versa, which may allow for storing quantum information prepared by future quantum computers. This method uses phonons, the sound equivalent of a photon, for storing quantum information because it's relatively easy to build small devices that can store these mechanical waves. The new method is independent of the properties of specific materials, making it compatible with established quantum devices, which are based on microwaves.
