Recently, a research team from the University of Science and Technology of China (USTC), headed by Professors Pan Jianwei, Lu Chaoyang, and Wang Hui, collaborated with Professor Ralph of the University of Queensland in Australia and Professor Renema from the University of Twente in the Netherlands. Together, they published a review article titled "Scalable Photonic Quantum Technologies" in Nature Materials.
This comprehensive study offers a systematic review of technologies pertaining to the generation, manipulation, and detection of photonic quantum states. It delves into the international advancements in quantum computing and simulation, quantum communication, and quantum precision measurement. Additionally, it presents insights into the future of large-scale photonic quantum computing, the development of global quantum networks, and the application of these technologies in quantum precision measurement.
Photons, as the fundamental carriers of quantum information, facilitate unconditionally secure key distribution in quantum communication. With the advent of satellite-to-ground fiber networks, real-time global transmission of quantum information is becoming increasingly feasible. In the realm of quantum computing, photonic quantum systems, known for their high manipulation precision and adaptability to various environments, are on the verge of achieving universal quantum computing at room temperature. Furthermore, in quantum precision measurement, photonic quantum squeezed states and entangled states have outperformed the standard quantum limit, proving instrumental in fields such as biomedicine and the precise definition of the International System of Units.
The team led by Professor Pan Jianwei has attained numerous internationally recognized achievements in photonic quantum information. These include the satellite-to-ground quantum communication experiment utilizing the "Micius" satellite, groundbreaking advancements in multi-photon entanglement and metrology technologies, and the "Jiuzhang" quantum computing prototype, which has repeatedly set new benchmarks for quantum computational superiority. This research endeavor has been supported by various institutions, including the Ministry of Science and Technology, the National Natural Science Foundation of China, and the Chinese Academy of Sciences.
