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 computing devices 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. Besides the general introduction of quantum simulation performed on this platform, I shall take quantum chemistry and dynamical quantum phase transition as examples to present the application of our system.


Professor 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, main results including high performance quantum magnetometer, Deterministic quantum teleportation between distant atomic objects. Afterwards, he moved to Rainer Blatt’s group as a postdoctoral research associate Institute for Quantum Optics and Quantum Information Austrian Academy of Sciences. The new field is quantum simulation based on trapped ions. In this year, 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 quantum systems. In 2020, he joined the Shanxi University and is building the lab for trapped-ion quantum simulation and computation & quantum metrology.
