芯片上的Penning离子阱：量子计算与精密测量

本课题组致力于芯片上的Penning离子阱技术研究，主要目标是为未来量子计算构建高性能的物理平台。我们已初步搭建了相关实验平台，并在此基础上，将Penning离子阱应用于量子精密测量。

Penning离子阱通过精密的电磁场将离子囚禁，使其在二维平面内形成离子晶体。这些离子晶体构成了独特的量子机械振子和转子系统，其能级是量子化的。利用这种二维量子谐振子，我们能够实现对极微弱力的测量，极限灵敏度有望达到 10E(−24)N。

• 参与芯片级离子阱的设计、制备与操控，掌握量子芯片的核心技术。
• 深入学习量子力学、电磁场理论以及低温物理等前沿知识。
• 锻炼精密光学、射频/微波电路设计与搭建、高真空系统等实验技能。
• 投身于量子计算、量子模拟以及量子精密测量等领域的开创性研究。

我们热忱欢迎对量子计算、芯片级量子器件、量子精密测量以及电磁场理论感兴趣的硕士生和博士生加入，共同探索量子世界的前沿！

On-chip Penning Ion Traps: Quantum Computing and Precision Measurement

Our group is dedicated to research on on-chip Penning ion trap technology, with the primary goal of building high-performance physical platforms for future quantum computing. We have already established the relevant experimental platform, and on this basis, we apply Penning ion traps to quantum precision measurement.

Penning ion traps confine ions through precise electromagnetic fields, causing them to form ion crystals in a two-dimensional plane. These ion crystals constitute unique quantum mechanical oscillator and rotor systems with quantized energy levels. Utilizing these two-dimensional quantum harmonic oscillators, we can achieve measurements of extremely weak forces, with a projected sensitivity limit of 10E(−24) N.

Join us, and you will have the opportunity to:

• Participate in the design, fabrication, and control of chip-scale ion traps, mastering core quantum chip technologies.
• Delve into cutting-edge knowledge in quantum mechanics, electromagnetic field theory, and low-temperature physics.
• Develop experimental skills in precision optics, RF/microwave circuit design and construction, and high-vacuum systems.
• Engage in groundbreaking research in quantum computing, quantum simulation, and quantum precision measurement.

We warmly welcome master's and doctoral students interested in quantum computing, chip-scale quantum devices, quantum precision measurement, and electromagnetic field theory to join us in exploring the frontiers of the quantum world!
