Yes, quantum transmission has been achieved in the lab. Quantum transmission is the transmission of quantum information through quantum teleportation, quantum entanglement and other technologies. In experiments, scientists have successfully achieved the transmission of quantum entanglement, including photons, ions and superconducting qubits. These experiments have brought important breakthroughs and advances in the development of fields such as quantum communication and quantum computing. However, the current quantum transmission technology still faces many challenges and needs further research and development.
Quantum transmission has already done a lot of experiments, the transmission distance has been greatly increased, it is only a matter of time and distance (longer and longer), China's research in this field in the world, is the top level.
