IBM研究人员宣布了一项重大突破：他们成功地用近1米长的超导铝电缆，将两块各含120个量子比特的Nighthawk量子芯片连接在一起，首次实现了跨芯片量子纠缠的可靠传输。量子计算被视为下一代计算技术，有望在药物研发、材料科学和密码破解等领域远超传统超级计算机。但量子芯片的规模扩展面临根本挑战——量子比特不能像普通晶体管那样密集排列。IBM的方案是将多个小芯片用超导电缆连接成模块化系统。尽管已有95%的纠缠保真度，但要实现实用的量子计算机仍有很长的路要走，包括跨冰箱远程连接、提高电缆可靠性等。专家认为，这是量子计算领域的重要里程碑。

A Breakthrough in Quantum Scaling

IBM researchers have achieved what many scientists thought was still years away: they connected two of their 120-qubit Nighthawk quantum chips using nearly one-meter-long superconducting aluminum cables. The experiment, conducted in a single liquid-helium refrigerator, demonstrates a practical path toward building quantum computers with thousands—or even millions—of quantum bits (qubits), capable of solving problems far beyond the reach of classical supercomputers.

IBM研究人员实现了许多科学家认为还需数年才能达到的成就：他们用近一米长的超导铝电缆，将两块各含120个量子比特的Nighthawk量子芯片连接在一起。这项在单台液氦冰箱中进行的实验，展示了一条构建拥有数千甚至数百万量子比特的量子计算机的可行路径。这种计算机能够解决远远超出传统超级计算机能力范围的问题。

Why connecting chips matters / 为什么连接芯片如此重要？ 

Quantum computing exploits quantum mechanical phenomena such as superposition and entanglement. Unlike classical bits that represent either 0 or 1, qubits can exist in both states simultaneously. This property enables quantum computers to explore many solutions to a problem in parallel. However, practical error correction requires spreading information from one fragile qubit across tens of thousands. The fundamental challenge: superconducting qubits cannot simply be packed more densely on a single chip, as miniaturization reduces the stability of their quantum states.

量子计算利用叠加态和纠缠等量子力学现象。不同于只能表示0或1的经典比特，量子比特可以同时处于两种状态。这一特性使量子计算机能够并行探索一个问题的多种解决方案。然而，实用的量子纠错需要将一个脆弱量子比特的信息分散到数万个量子比特上。根本的挑战在于：超导量子比特不能简单地在一块芯片上密集排列，因为微型化会降低其量子态的稳定性。

How IBM solved the problem / IBM如何解决这一难题？ 

To address this constraint, IBM adopted a modular architecture conceptually similar to how multi-core processors work today. Instead of squeezing more qubits onto one chip, they envision linking multiple chips with high-quality superconducting connections. The new design incorporates four aluminum cables (80 centimeters each) connecting two Nighthawk chips. The connection mechanism is elegantly simple: spring-loaded connectors compress a small blob of indium—a soft, superconducting metal—between the cable and the chip, creating a reliable superconducting path.

为应对这一限制，IBM采用了一种模块化架构，其概念类似于当今多核处理器的工作方式。他们不再在一块芯片上挤压更多量子比特，而是设想用高质量的超导连接将多块芯片串联起来。新设计包含四根铝电缆（每根80厘米），连接两块Nighthawk芯片。连接机制简洁优雅：弹簧加载的连接器将一小块铟（一种软的超导金属）压缩在电缆与芯片之间，形成可靠的超导通路。

The results and remaining challenges / 实验结果与未来挑战 

By tuning adjustable qubits at each end of the cable to matching frequencies, researchers successfully swapped quantum states between the two chips. With further manipulation, they achieved two-qubit entanglement with 95% fidelity across the interconnection. Larger entangled states comprising up to three qubits on each chip were also created. Despite this impressive milestone, significant obstacles remain. The fidelity drops when all four cables operate simultaneously. More critically, IBM has yet to demonstrate chips connected across separate cryogenic systems—a necessary step for true scalability.

通过将电缆两端可调量子比特调至匹配的频率，研究人员成功地在两块芯片之间交换了量子态。经过进一步操作，他们实现了跨互连的双量子比特纠缠，保真度达到95%。还创建了每块芯片包含最多三个量子比特的更大纠缠态。尽管这是一项令人印象深刻的里程碑，但仍存在重大障碍。当四根电缆同时工作时，保真度会下降。更关键的是，IBM尚未展示在不同低温系统之间连接的芯片——这是真正实现可扩展性的必要步骤。

思考题 Discussion Questions

1. The article says practical quantum computing requires 100,000 to 1,000,000 qubits. If we only have chips with 120 qubits each, how many chips would we need for a large-scale system?

2. Some scientists worry that powerful quantum computers could break modern encryption codes used to protect banking and Internet security. Do you think this risk outweighs the benefits of quantum computing? Why or why not?
