报 告 人：申恒 牛顿学者研究员
Heng Shen obtained his PhD degree in 2015 in Niles Bohr Institute at Copenhagen University, under the supervision of Prof. Eugene Polzik. His PhD work is focused on spin squeezing and entanglement with room temperature atoms. Afterwards, he moved to Rainer Blatt’s group as a postdoctoral research associate in IQOQI, Austrian Academy of Sciences, focusing on quantum simulation based on trapped ions. In 2017, he received the Newton International Fellowship to move to Oxford University as a researcher assistant, mainly focus on Quantum state engineering of hybrid spin-mechanical system.
Quantum computers hold the promise to solve certain problems exponentially faster than their classical counterparts. Trapped atomic ions are among the physical systems in which building such a computing device seems viable. In this talk I shall present a small-scale quantum information processor based on a string of 40Ca+ ions confined in a macroscopic linear Paul trap. Two projects are involved in my talk. The first topic here pursues quantum chemistry simulation and the second explores dynamical phase transitions.
