Quantum teleportation from light beams to vibrational states of a macroscopic diamond
Abstract
With the recent development of optomechanics, the vibration in solids, involving collective motion of trillions of atoms, gradually enters into the realm of quantum control. Here, building on the recent remarkable progress in optical control of motional states of diamonds, we report an experimental demonstration of quantum teleportation from light beams to vibrational states of a macroscopic diamond under ambient conditions. Through quantum process tomography, we demonstrate average teleportation fidelity (90.6±1.0)%, clearly exceeding the classical limit of 2/3. The experiment pushes the target of quantum teleportation to the biggest object so far, with interesting implications for optomechanical quantum control and quantum information science.

Two methods can be adopted to circumvent noisy channels: increasing resilience to losses and noise with two-way classical communications, or decreasing their influence by encoding information in decoherence-free subspaces.
“Two methods can be adopted to circumvent the issue of noisy channels: to increase the resilience of a protocol to losses and noise [380][381][382] (two-way classical communications), or to decrease their influence by encoding information in immune states (decoherence-free subspaces, DFS), for both quantum computation [383] and quantum communication tasks [384].”
From Photonic quantum information processing: a review (2019) · cites this paper as [384]
The citation appears to support using decoherence-free subspaces for quantum communication. The Results (Photon-to-phonon teleportation scheme; Experimental realization of teleportation) describe teleportation and measured noise, but do not describe encoding information in decoherence-free subspaces to protect it from noisy channels. Searches for decoherence-free subspaces and protected encoding found no passage addressing that method. (LLM, conf=0.74)

“Similar to the pioneering teleportation experiment of photons [5], our implementation of teleportation is conditional as the Bell measurements are not deterministic and require postselecting of successful measurement outcomes.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
