A team of Chinese scientists has carried out the world’s largest quantum ion trap simulation with single-qubit resolution accuracy, marking a significant leap forward in the quest for large-scale quantum computing capabilities.

The ion trap, a device that confines ions within a confined space using electromagnetic fields, stands out as a highly promising candidate for realizing large-scale quantum computing.

However, the main challenge in this approach is to simultaneously maintain stable ion capture and precise control over a large number of ions.

Quantum simulations involving approximately 200 ions have been reported. However, the inability to discern the state of individual ions has prevented the extraction of vital data, posing a barrier to advancing more extensive and versatile quantum computing applications in the future.

Using cryogenic monolithic ion trap technology and a two-dimensional scheme, researchers at Tsinghua University have achieved stable 512 ion trapping for the first time.

Additionally, the team successfully conducted quantum state measurements with “single-qubit resolution” on an unprecedented 300 ions, according to the study published Thursday in the journal Nature.

“This work is the largest simulation or quantum computation carried out to date on a trapped ion system. This is a milestone to be recognized”, commented the article reviewer.

“Our work provides a powerful tool to delve deeper into the intricacies of quantum science and pave the way for the advent of large-scale quantum computing,” said Duan Luming, corresponding author of the paper.

“This innovation has the potential to be applied in areas such as materials and pharmaceutical product development, engineering and artificial intelligence,” said Duan.
