Quantum teleportation is an important prototype operation in the field of quantum communication and quantum computing. It uses quantum entanglement and classical communication to transfer complete quantum state information from one physical system to another. Since the concept of quantum teleportation has been proposed for more than two decades, it has been a research hotspot in the field of quantum information physics. Scientists from all over the world are competing to realize quantum teleportation schemes in different microscopic physical systems as system quantum coherence. Proof of regulatory capacity. To date, quantum teleportation has been demonstrated and demonstrated between photons, between individual ions, atoms, or groups of atoms, and between solid qubits.
It is hoped that the object of quantum teleportation will be advanced to a more macroscopic object, beyond the limits of the microscopic world, to achieve quantum coherent regulation of the macroscopic system. For the first time, Duan Luming's research group realized quantum teleportation of the quantum vibration mode of a quantum state from a microscopic particle (single photon) to a macroscopic object at a normal temperature (a diamond sample of centimeter size), propelling the object of the implicit transmission to the largest macroscopic object to date. This work represents an important research advance in the field of quantum coherence regulation.

Tsinghua University News Network, June 3rd, Professor Duan Luming, Research Institute of Tsinghua University, has made significant progress in the field of quantum information, and for the first time realized quantum teleportation from photon to macroscopic diamond vibration mode. The research paper "Quantum teleportation from light beams to vibrational states of a macroscopic diamond" was recently published in the natural issue "Nature Communications". A schematic diagram of quantum entanglement of photon and macroscopic diamond collective vibration modes (phonons) using ultrafast lasers.
The fidelity of quantum hidden transmission (~90%) is significantly higher than the classical limit of 66.7%.
The experiment used a unique design to encode different vibration modes in diamond into qubits, using ultrafast femtosecond lasers to create entanglement of photons and diamond vibrato phonons. The entanglement between photons and diamond vibrating phonons is used to transmit the polarization bits of the photons into the vibration mode in the diamond. The experimental group completed the cryptic transmission of multiple complementary quantum states, the average fidelity is over 90%, which is much higher than the classical limit of 66.7%. The quantum property of the cryptic transmission is fully verified, and the quantum coherence of the macro-temperature diamond samples at room temperature is realized. Regulation. The paper was unanimously recommended by three reviewers, calling it an "exciting progress" in this field.
