How splitting sound might lead to a new frontier of quantum computing

A quantum computer using phonons could be very compact and self-contained, built entirely on a chip similar to that of a laptop computer’s processor.

When you turn on a lamp to brighten a room, you are experiencing light energy transmitted as photons, which are small, discrete quantum packets of energy. These photons must obey the sometimes strange laws of quantum mechanics, which, for instance, dictate that photons are indivisible, but at the same time, allow a photon to be in two places at once.
