摘要:Telecom-band-integrated quantum memory is an elementary building block for developing quantum networks compatible with fiber communication infrastructures. Towards such a network with large capacity, an integrated multimode photonic quantum memory at telecom band has yet been demonstrated. Here we report a fiber integrated multimode quantum storage of single photon at telecom band on a laser-written chip. The storage device is a fiber-pigtailed Er3+:LiNbO3 waveguide and allows a storage of up to 330 temporal mode of heralded single photon with 4-GHz-wide bandwidth at 1532 nm. Our memory system with all-fiber addressing is performed using telecom-band fiber-integrated and on-chip devices. The results represent an important step for the future quantum networks using integrated photonics devices.

简历Dr. Qiang Zhou received his B.S. degree in optoelectronic information from the University of Electronic Science and Technology of China (UESTC), Chengdu, China, in 2006, and his Ph.D. degree in electronic science and technology from Tsinghua University, Beijing, China, in 2011. From 2014 to 2017, he was a postdoctoral fellow with the Department of Physics and Astronomy, Institute for Quantum Science and Technology, University of Calgary, Calgary, AB, Canada. He is currently a full professor with UESTC. His current research interests include quantum information technologies, quantum internets, quantum computation, quantum photonics, quantum optics, communication systems, fiber sensing, and nano-photonics.
