Prof. Guangcan Guo’s staff from CAS and USTC printed an in-depth overview on quantum teleportation, highlighting its significance in quantum communication and computing. The staff’s developments embody making a high-fidelity 32-dimensional quantum entanglement and its profitable transmission over lengthy distances, with the paper additionally discussing quantum expertise’s future sensible growth.
A staff led by Academician Prof. Guangcan Guo from the Chinese Academy of Sciences (CAS) offers a complete overview of the progress achieved within the discipline of quantum teleportation. The staff, which incorporates Prof. Xiaomin Hu, Prof. Yu Guo, Prof. Biheng Liu, and Prof. Chuanfeng Li from the University of Science and Technology of China (USTC), CAS, was invited to publish a overview paper on quantum teleportation within the peer-reviewed scientific journal Nature Review Physics. The paper was formally launched on-line on May 24.
As one of the crucial necessary protocols within the discipline of quantum data, quantum teleportation has attracted nice consideration because it was proposed in 1993. Through entanglement distribution and Bell-state measurement, quantum teleportation permits the nonlocal transmission of an unknown quantum state, which has deepened the understanding of quantum entanglement. More importantly, quantum teleportation can successfully overcome the space limitation of direct transmission of quantum states in quantum communication, in addition to understand long-range interactions between completely different quantum bits in quantum computing.
The team, under the leadership of Prof. Biheng Liu and Prof. Chuanfeng Li, has been at the forefront of experimental studies on high-dimensional quantum teleportation and quantum networks. Their notable achievements include the successful preparation of the world’s highest fidelity 32-dimensional quantum entanglement, the effective transmission of high-dimensional entanglement over 11 kilometers of optical fiber, and the development of efficient techniques for quantum entanglement detection. They have also made significant progress in areas such as high-dimensional quantum dense coding, high-dimensional quantum guidance, and high-dimensional quantum teleportation.
Based on the important progress made by the research group over the years in high-dimensional quantum teleportation and high-dimensional quantum communication, Dr. Iulia Georgescu, chief editor of Nature Review Physics, invited Guo’s team to write a review paper about advances in quantum teleportation.
Teleportation has advanced a lot in both theoretical research and experimental verification. It is currently at the critical stage from proof-of-principle to practical application. This paper discussed potential applications and future development in quantum communication and quantum computing in depth, which will promote the practical development of quantum technology.
