Title: Quantum Interconnects with atomic platforms
Speaker: Yan-Cheng Wei (NTU, Physics)
Abstract: With the rapid development of quantum computing, it is necessary to further develop the technology to interconnect different local nodes and facilitate their powers—similar to the fact that “classical” internet connects computers distributed over different places [1, 2]. However, different from the classical one, quantum interconnects require transferring quantum information, which is fragile and cannot be replicated, in coherent manners. To date, the goal remains challenging and requires intensive efforts to develop efficient routing schemes, and it needs collaborative efforts including physics, engineering, and computer science. In this talk, I will focus on experimental physics side.I will report results using cold-atom-based platforms, including transduction, broadband quantum storage, single-photon-based memory. I will also identify some intrinsic challenges and briefly introduce other potential platforms that may lead to more scalable state transfer.
Yan-Cheng Wei is a research assistant in Prof. Hsi-Sheng Goan’s group and Prof. Ying-Cheng Chen’s group. He will be a Ph.D. student at Harvard University.
