How splitting sound could lead to a new kind of quantum computer

When you turn on a lamp to light up a room, you’re experiencing light energy transmitted as photons, which are small, discrete quantum packets of energy. These photons have to obey the sometimes strange laws of quantum mechanics, which, for example, dictate that photons are indivisible, but at the same time allow a photon to … Read more

A diagram showing a line representing a beam splitter, hitting a phonon. Two dashed lines on either side of the beam splitter line indicate that the phonon is both reflected from the beam splitter and transmitted to the other side, superimposed.
