Context:
According to a paper published in Science, it is possible to build a quantum computer whose information unit is sound/phonon
About Phonon:
- A phonon is a definite discrete unit or quantum of vibrational mechanical energy, just as a photon is a quantum of electromagnetic or light energy.
- Phonons and electrons are the two main types of elementary particles or excitations in solids.
- Whereas electrons are responsible for the electrical properties of materials, phonons determine such things as the speed of sound within a material and how much heat it takes to change its temperature.
