  Proposing a combined system of a nanoparticle and a plane surface in the
presence of electromagnetic vacuum fluctuations, the electromagnetic and medium
fields have been quantized. Quantum friction of nanoparticle due to the
presence of plane surface and also electromagnetic vacuum has been discussed.
The possibility of synchronizing rotating bodies through the quantum friction
between them are investigated. It has been shown that there is a significant
connection between the synchronization of the rotating bodies and their quantum
friction.
