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 ...
