Phonons are to sound what photons are to light. Photons are tiny packets of energy for light or electromagnetic waves. Similarly, phonons are packets of energy for sound waves. Each phonon represents the vibration of millions of atoms within a material. 

Both photons and phonons are of central interest to quantum computing research, which exploits the properties of these quantum particles. However, phonons have proven challenging to study due to their susceptibility to noise and issues with scalability and detection. 

Now, in a breakthrough study, scientists have successfully split phonons paving the path for a new type of quantum computer called linear mechanical quantum computers.
