A team led by Prof. Guangcan Guo from the Chinese Academy of Sciences (CAS) and the University of Science and Technology of China (USTC) recently delivered an exhaustive analysis on quantum teleportation, emphasizing its significance in quantum communication and computation. The group’s breakthroughs include generating a 32-dimensional quantum entanglement of high fidelity and its successful long-range transmission. The paper also explores the future tangible growth of quantum technology.
The research group under the direction of Prof. Guangcan Guo, including Prof. Xiaomin Hu, Prof. Yu Guo, Prof. Biheng Liu, and Prof. Chuanfeng Li, were welcomed to contribute a review paper to the peer-reviewed scientific journal, Nature Review Physics. The paper, which provides a thorough survey of the advances in the sphere of quantum teleportation, was officially made available online on May 24th.
Quantum teleportation, one of the most significant processes in quantum information, has captivated substantial interest since its proposal in 1993. By leveraging entanglement distribution and Bell-state measurement, quantum teleportation facilitates the remote transmission of an unknown quantum state, which has led to a profound comprehension of quantum entanglement. Of particular importance is the ability of quantum teleportation to conquer distance restrictions in the direct transmission of quantum states for quantum communication and to enable long-range interactions between different quantum bits for quantum computing.
The researchers, under the guidance of Prof. Biheng Liu and Prof. Chuanfeng Li, have been pioneers in experimental research on high-dimensional quantum teleportation and quantum networks. Their remarkable achievements encompass the successful creation of the world’s highest fidelity 32-dimensional quantum entanglement, effective transmission of high-dimensional entanglement over an 11-kilometer optical fiber span, and the development of efficient techniques for quantum entanglement detection. Significant strides have also been made in areas like high-dimensional quantum dense coding, high-dimensional quantum guidance, and high-dimensional quantum teleportation.
Dr. Iulia Georgescu, the chief editor of Nature Review Physics, invited Guo’s team to author a review paper, inspired by the noteworthy progress the research group has made over the years in high-dimensional quantum teleportation and communication.
The field of teleportation has witnessed substantial progression in both theoretical research and experimental confirmation. It currently stands at the pivotal juncture from principle demonstration to practical implementation. The paper deeply discusses prospective applications and future growth in quantum communication and quantum computing, propelling the practical evolution of quantum technology.
