克服运行中原子损耗限制,能自行修复的量子计算机问世
Huan Qiu Wang Zi Xun· 2025-12-23 01:30
为解决这一问题,研究团队想出了"分区管理"的办法。他们把原子分成5个不同的功能区:寄存区用于存放量子比特,交互区进行计算,测量区用于利用辅 助原子检查误差,储备区则放着备用原子,加载区负责从外部补充新原子。 这样一来,就好比把工厂的生产线分成几个独立车间,即便某个车间出现故障,其他车间仍能照常运转,不会让整个生产停摆。当"工厂"发现某个原子"跑 掉"时,会立即从储备区调出备用原子,放到空缺位置,并将其重置为最低能量状态,使其马上投入运算。同时,完成检查任务的辅助原子也可以被回收, 经过重置后重复使用,实现"边运行边修复"。 为了验证这一机制,研究团队让量子计算机运行了一个重复代码,并连续进行了41轮自检。每轮中,系统都能像替换损坏零件一样,及时补上丢失的原子, 而数据运行不受影响。研究人员表示,如果没有自我修复功能,系统在几轮运算后就会"耗光原子",无法继续工作。 这项研究表明,中性原子量子处理器在电路运行中可像"回收零件"一样,重新初始化并重复使用辅助原子,这样在量子比特寿命有限的条件下,量子电路也 能连续运转。 来源:科技日报 科技日报记者 张佳欣 就像传统计算机一样,量子计算机也会"出故障"。在运行过程 ...

Summary of Quantum Computing Industry Conference Call Industry Overview - The conference call focused on the **quantum computing industry**, discussing various technological routes and advancements in quantum computing, including superconducting, ion trap, neutral atom, and photonic technologies [1][2][3]. Key Points and Arguments Technological Routes - **Superconducting Technology**: - Leading in engineering progress but requires improvement in yield rates. Companies like Benyuan and IBM can produce over 100 to thousands of qubits [1][3][4]. - **Ion Trap Technology**: - High fidelity with single and two-qubit logic gates achieving 99.99%. Companies like Beijing Huayi and Anhui Yao are actively developing this technology [3][10]. - **Neutral Atom Technology**: - Significant progress in trapping a large number of qubits, with reports of up to 6,100 qubits. Wuhan Zhongke Kuyuan is a notable player in this field [1][11]. - **Photonic Technology**: - Simple construction but requires a large number of auxiliary qubits for error correction. Companies like Shanghai Turing and Beijing Bosi are making strides in this area [1][12]. Quantum Supremacy - "Quantum supremacy" refers to quantum computers outperforming classical computers in specific tasks. Google's achievement using 53 qubits to solve a random circuit sampling problem in 200 seconds, compared to classical computers taking thousands of years, exemplifies this [1][6][22]. Current State and Future Prospects - Quantum computing is currently in a medium noise stage, with commercial applications beginning to emerge. Full-scale practical applications are expected in 8 to 10 years, although advancements from companies like Google and IONQ may shorten this timeline [2][18][19]. Challenges in Quantum Computing - **Superconducting Quantum Computers**: - Face challenges such as the complexity of internal layouts due to increased qubit numbers and difficulties in interconnecting multiple devices [9]. - **Ion Trap Systems**: - Require high precision in laser control and face engineering challenges in trapping more ions [10]. - **Neutral Atom Systems**: - Still in the early stages with limited startups, but potential for growth as research progresses [11]. - **Photonic Systems**: - Need significant auxiliary qubits for error correction, complicating their practical application [12]. Important but Overlooked Content - The Chinese quantum computing industry has room for improvement compared to international counterparts, particularly in measurement and control systems, stability of dilution refrigerators, and integration of quantum chips [2][13][14]. - The government is providing substantial support for quantum technology development, with funding for national laboratories and regional initiatives [20][21]. - Companies like Hefei's data center have begun purchasing quantum computers for research and development, indicating a growing interest in practical applications [19]. Conclusion - The quantum computing industry is rapidly evolving, with various companies making significant advancements across different technological routes. However, challenges remain in terms of engineering, integration, and commercial viability. The support from government and academic institutions is crucial for the continued growth and success of this industry.
