    "abstract": "We propose a spectroscopic approach to probe tiny vibrations of a\nnanomechanical resonator (NAMR), which may reveal classical or quantum behavior\ndepending on the decoherence-inducing environment. Our proposal is based on the\ndetection of the voltage-fluctuation spectrum in a superconducting transmission\nline resonator (TLR), which is {\\it indirectly} coupled to the NAMR via a\ncontrollable Josephson qubit acting as a quantum transducer. The classical\n(quantum mechanical) vibrations of the NAMR induce symmetric (asymmetric) Stark\nshifts of the qubit levels, which can be measured by the voltage fluctuations\nin the TLR. Thus, the motion of the NAMR, including if it is quantum mechanical\nor not, could be probed by detecting the voltage-fluctuation spectrum of the\nTLR.",
