QC WORKSHOP 18: Quantum Simulation Using Atoms and Ions

在过去的二十年里,用于研究多体系统的量子模拟和计算方法发展出了两类互补的方案。自上而下的方案通过对多粒子体系进行全局相互作用来模拟匀质体系。自下而上的方案通过整合多个可被高精度控制的粒子来构建大型系统。本次报告将介绍属于自上而下方案的玻色-爱因斯坦凝聚体量子模拟系统和属于自下而上方案的离子阱量子计算系统。在介绍技术细节的基础上,我们将进一步讨论应用这些体系来研究多种物理问题。

Quantum Simulation and computation on many-body systems has branched to two complementary strategies over the last two decades. The top-down strategy uses ensembles of many particles with control over global interactions, where the granular details can be ignored and the ensemble can be treated as a smooth medium. The bottom-up strategy uses high-fidelity control over individual particles and builds large many-body systems by assembling them together. In this talk, I will talk about both approaches with Bose-Einstein condensates in the top-down approach and trapped ions in the bottom-up approach. Building on the interacting atomic quantum system, we will talk about investigating interesting physics ranging from condensed matter to cosmology, such as quantum phase transition, spin domain confinement, many-body localizations and even Unruh radiations.

主讲人介绍: Dr. Lei Feng works on quantum simulation and quantum computing at Duke University. His current postdoctoral research focuses on building a new generation of programmable quantum computing platform using trapped Yb ions. Lei got his Ph.D. in physics from the University of Chicago on quantum simulation using ultra-cold neutral atoms, where Bose-Einstein Condensation is used to study phase transitions and matter-wave radiations. He is also a winner of Sidney Nagel Prize for Creativity in Research and the OCPA Outstanding Dissertation Award.
