Chinese researchers have successfully trapped 512 ions in a two-dimensional Wigner crystal and performed quantum simulations utilizing 300 of those ions as qubits. According to the researchers, this demonstrates the largest quantum simulator based on trapped ions achieved to date. The research was led by quantum physicist Duan Luming at Tsinghua University, who recently returned to China, after teaching in the US.
Chinese researchers report that they have successfully trapped 512 ions in a two-dimensional Wigner crystal and performed quantum simulations using 300 of those ions as qubits. The researchers report that the experiment, published recently in the journal Nature, demonstrates the largest quantum simulator based on trapped ions achieved to date.
According to the study, the team made headway on two crucial quantum computing requirements: “A large qubit capacity and an individual readout capability are two crucial requirements for large-scale quantum computing and simulation. As one of the leading physical platforms for quantum information processing, the ion trap has achieved a quantum simulation of tens of ions with site-resolved readout in a one-dimensional Paul trap and of hundreds of ions with global observables in a two-dimensional (2D) Penning trap. However, integrating these two features into a single system is still very challenging.”
