In this paper, we report an experimental demonstration of quantum teleportation from light beams to the vibrational states of a macroscopic diamond sample of 1 mm in size under ambient conditions. The vibration states are carried by two optical phonon modes, representing collective oscillation of over 1 carbon atoms. To facilitate convenient qubit operations, we use the dual-rail representation of qubits instead of the single-rail encoding used in the previous experiments and generate entanglement between the paths of a photon and different oscillation patterns of the diamond represented by two phononic modes. Using quantum state tomography, we demonstrate entanglement fidelity of (81.0±1.8)% with the raw data and of
(89.7±1.2)% after the background noise subtraction.
