We propose a current correlation spectrum approach to probe the quantum behaviors of a nanomechanical resonator (NAMR). The NAMR is coupled to a double quantum dot (DQD) which acts as a quantum transducer and is further coupled to a quantum point contact (QPC). By measuring the current correlation spectrum of the QPC, shifts of the DQD energy levels which depend on the phonon occupation in the NAMR can be determined. Quantum behaviors of the NAMR can thus be observed. In particular, the cooling of the NAMR into the quantum regime can be examined. In addition, the effects of the coupling strength between the DQD and the NAMR on these energy shifts are studied. We also investigate the impacts on the current correlation spectrum of the QPC due to the backaction from the charge detector on the DQD.
