Abstract:
Quantum computing platforms based on single-atom array trapped by optical tweezers have recently emerged as a competitive modality due to a direct path toward high qubit count, rapidly advancing gate fidelity, and their ability to execute quantum circuits with arbitrary qubit connectivity. Significant progresses have been made towards fault-tolerant universal quantum computing. As an example, a recent work utilizing quantum error correction demonstrated that logical quantum information （quantum memory） can be maintained in such a system of over 3 minutes, even though underlying physical qubits have lifetimes of 10 seconds [1]. In this talk, I will introduce the basic principle and status of quantum computing based on neutral atoms, as well as our development along this direction and future plan.

Biography:
Ying-Cheng Chen （陳應誠） is a research fellow of Institute of Atomic and Molecular Sciences, Academia Sinica. He is also an adjunct professor of Graduate Institute of Applied Physics, NCCU. He received his Ph.D. from NTHU in 2002 and did his postdoctoral research in Rice University to 2004. He joined IAMS in 2005. At IAMS, his main research areas are realization of high-performance optical quantum memory for quantum communication, cooperative radiation phenomena such as super-radiance and sub-radiance and quantum computing and simulation based on single atom array. He has realized a world-record efficiency of quantum memory based on electromagnetically induced transparency with cold atomic ensembles. In recent year, he led a national quantum project aiming at building a quantum processor based on neutral atoms.
