Probing Tiny Motions of Nanomechanical Resonators: Classical or Quantum Mechanical?
Probing Tiny Motions of Nanomechanical Resonators: Classical or Quantum Mechanical?
We propose a spectroscopic approach to probe tiny vibrations of a nanomechanical resonator (NAMR), which may reveal classical or quantum behavior depending on the decoherence-inducing environment. Our proposal is based on the detection of the voltage-fluctuation spectrum in a superconducting transmission line resonator (TLR), which is {\it indirectly} coupled to …
