Abstract

Synchronization phenomena have been observed in a broad range of physical, chemical and biological systems but there are few attempts to describe them in the quantum regime. Most of the attention in this regime has been devoted to the problem of entrainment induced by an external driving [1] and not to spontaneous synchronization. We also mention recent research by different groups on synchronization of nano/microscopic systems [2]. Even if these works [2] are concerned with classical (average) properties, such optomechanical devices are indeed susceptible of having quantum behaviour, being the subject of an intense experimental effort. In [3], for the first time, we established the connections between the phenomenon of synchronization and quantum correlations.
