(Yicai) July 11 -- Pan Jianwei, Chen Yu'ao, Yao Xingcan, and Deng Youjin from the University of Science and Technology of China have built a quantum simulator with ultracold atoms for solving the fermionic Hubbard model, opening up new possibilities for developing specialized quantum simulators.

The team has observed the antiferromagnetic phase transition within a quantum simulator of the FHM for the first time, according to research findings published in the international academic journal Nature yesterday.

The simulator, whose simulation capabilities surpass those of classical computers, is a major first step towards obtaining the low-temperature phase diagram of the model and understanding the role of quantum magnetism in the mechanism of high-temperature superconductivity.

The discovery has propelled China to the forefront of global research in using ultracold atom-specific quantum simulations to study the mechanisms of high-temperature superconductivity.

The FHM is considered a promising core physical model for explaining the mechanism of high-temperature superconductivity, a problem that has perplexed the physics community for nearly forty years. Once its physical mechanism is understood, it will be possible to design, produce, and apply new high-temperature superconducting materials on a large scale, leading to transformative impacts in power transmission, medicine, supercomputing, and other fields.

According to Pan, China will be able to develop several dedicated quantum computers capable of addressing the needs of material design, chemical research, and physical research within five to ten years.

Nature's reviewers have given high praise to the Chinese team's work, noting that it has the potential to become a milestone and significant breakthrough in modern technology and marks an important step forward in the field.

This discovery holds significant scientific value and possesses immense potential for economic benefits, Chen told Yicai. It will propel the future study of the mechanisms behind strongly correlated quantum materials represented by high-temperature superconductors, Chen pointed out.

Quantum technology has become an important strategic and competitive field among major countries. "I hope to leverage the construction of national laboratories and concentrate the efforts of China to tackle quantum computers and break through the blockade imposed by foreign countries," Pan said regarding intense future competition.
