Abstract

Decoherence is a major challenge in quantum computing. To enable execution of quantum al- gorithms, it is crucial to eliminate decoherence and noise for instance via dynamic decoupling and quantum error correction protocols based on dynamic zero-noise strategy. As potential alternatives we introduced self-protected quantum algorithms over 15 years ago. Quantum algorithms of this kind, based on the living-with-noise strategy, are now used in the Noisy Intermediate-Scale Quantum regime. I will briefly introduce the strategy of self-protectiveness and focus on self-protected quantum simulation in the presence of classical noise.

Biography

Lianao Wu received his Ph.D in Physics from Jilin University in 1989 and did his postdoctoral research at Tennessee University, USA (1991). Then he served as an associate professor and full professor at the Department of Physics, Jilin University, China (1991-1999). His research interests then included: quantum many-body problems of nuclear system and condensed matter, fundamental problems of quantum mechanics, computational physics, and molecular physics. He was a visiting professor in Research Center for Nuclear Physics, Osaka, Japan (1996 – 1997), with research fields includling theoretical and computational quantum many-body problem. He worked as an Alexander von Humboldt Fellow at the Department of Physics, Munich Technology University, Germany (1999-2000), when his research focused on theoretical and computational quantum many-body problems. During the year 2000 to 2008, He was a research associate/researcher in Center for Quantum Information & Quantum Control, University of Toronto, Canada, when his research focused on quantum computation. He became an Ikerbasque Professor in Ikerbasque Foundation and Department of Physics, The Basque Country University, Spain (2008 – present). His research interests are on quantum computation, quantum information, control and quantum devices.
