| Description |
Quantum mechanics has been well-tested at atomic scales, in optical and electronic systems. In recent years, there has been significant interest to demonstrate that quantum mechanics also applies to mechanical systems. We are trying to verify this by studying the interactions between a nanomechanical oscillator (NMO) and a single spin. In our system, the NMO is coupled to the electronic spin of a Nitrogen-Vacancy (NV) center in a nanodiamond through a uniform external magnetic field. We use this coupling to make quantum non-demolition (QND) measurements of the oscillator and spin states, enabling a bridge between the quantum and classical worlds for a simple readout of the NV center spin and observation of the discrete states of the NMO. A quantum mechanical analysis of the interaction and preliminary fabrication and detection results will be presented.
