Quantum Cascade Laser Frequency Comb (QCL-FC), as an emerging solid-state radiation source operating in the mid-infrared to terahertz spectral ranges, has attracted widespread attention for its application in fields such as rapid spectroscopy, sensing, and lidar.

Experimentally realizing novel quantum phases of matter and manipulating their properties is a centr

Recently, the ultrafast spectroscopy team at the Beijing Academy of Quantum Information Sciences (BAQIS) achieved the room-temperature optical spin Hall effect of exciton-polaritons in a formamidinium lead bromide (FAPbBr3) perovskite microcavity.

Since its launch in 2023 by the Beijing Academy of Quantum Information Sciences (BAQIS), Quafu has consistently adhered to principles of openness, stability, and high quality, providing free, high-performance cloud quantum computing services to users worldwide, earning widespread recognition from users around the world.
