The development of small and scalable solid state quantum systems, where quantum manipulations are possible, is essential for quantum information science. However, unlike a trapped atom system, it is very difficult to isolate a solid state quantum system from thermal disturbances. Cryogenic technology and nanofabrication technology make a mechanical oscillator a likely candidate for a new solid state quantum system. It has been possible to cool mesoscale oscillators down to the quantum ground state using radiation pressure. In this article, the physics of laser cooling of mechanical oscillators with photonic crystal nanocavities is introduced with the future prospects of this field.
