In recent years, the development of quantum computers has become a must for global scientific and technological strategies, and the development of quantum chips is the core of quantum computer research.
On the morning of December 17, Zhejiang University released the "Mogan No. 1" and "Tianmu No. 1" superconducting quantum chips, which correspond to the famous mountains in Zhejiang: Moganshan and Tianmushan respectively.
It is understood that the "Mogan No. 1" and "Tianmu No. 1" released this time are two superconducting quantum chips based on different architectures.
Among them, "Mogan No. 1" is a dedicated quantum chip that adopts a fully connected architecture, which is suitable for achieving quantum simulation and precise regulation of quantum states for specific problems.
The research team used the "Mogan No. 1" chip to systematically study the widely concerned topic of Stark multibody localization in quantum multibody physics.
The use of superconducting quantum chips to simulate quantum multibody systems is an exciting field, which is different from classical numerical simulations based on supercomputers, and is a new research method that will greatly promote the study of complex multibody systems.
The "Tianmu No. 1" chip is oriented to general-purpose quantum computing and adopts a relatively easy-to-expand near-neighbor connectivity architecture.
In order to perform a relatively complex quantum gate algorithm, a total of 36 superconducting qubits with longer bit life are integrated on "Tianmu 1", realizing a high-fidelity universal quantum gate.
Compared with "Mogan No. 1", "Tianmu No. 1" has higher programming flexibility to perform more kinds of quantum algorithms, which can be applied to more research fields.
The R&D team of "Mogan No. 1" and "Tianmu No. 1" is led by Academician Zhu Shiyao, an expert in quantum optics, a professor in the Department of Physics of Zhejiang University, and the chief scientist of the Quantum Computing Innovation Workshop of the Science and Technology Innovation Center. Academician Zhu said that China has reached the world's advanced level in some aspects of quantum information and quantum communication.
It is worth mentioning that at present, the R & D team already has a full-stack R&D capability from superconducting quantum chip design, preparation, packaging to measurement and control, "Mogan No. 1" and "Tianmu No. 1" are independently developed and prepared by the team.
