Phonons

June 21, 2023

Scientists have successfully split phonons, demonstrating their quantum properties and ability to manipulate and control quantum states.
- Achievement may lead to development of sound-based versions of quantum computers or extremely sensitive measuring devices in future.
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.
These are quasiparticles that represent collective vibrations of atoms or molecules in a solid material.
These are packets of energy for sound waves.
These need a medium such as air or water.
Phonons of different wavelengths can interact and mix when they bump into each other, producing a different wavelength.
