量子计算目前处于早期发展阶段，类似于一九四十年代庞大的Eniac电脑，但它正逼近一项重大突破。这项技术有望彻底改变药物研发、物流优化以及网路安全等领域的未来发展。（关键数字：1940）

量子电脑使用量子位元，能同时处于零与一的叠加状态，从而提供指数级的运算能力。然而，它们对热量和震动等环境因素极为敏感，容易产生错误，因此需要透过建立逻辑量子位元来进行错误更正。

业界普遍认为，达到一百个具备纠错能力的逻辑量子位元是超越传统电脑的重要门槛。Quantinuum、IBM与Infleqtion等公司正迅速朝此目标迈进，预计在不久的将来达成，宣告量子计算时代的真正来临。

Quantum computing is currently in its early developmental stages, similar to the massive Eniac computers of the 1940s, but it is approaching a major breakthrough. This technology holds the promise of revolutionizing fields such as drug discovery, logistics optimization, and cybersecurity in the future.

Quantum computers utilize qubits that can exist in a superposition of both zero and one simultaneously, thereby providing exponential computational power. However, they are highly sensitive to environmental factors like heat and vibrations, which easily cause errors, making the creation of error-correcting logical qubits essential.

The industry generally considers reaching one hundred error-corrected logical qubits as the crucial threshold for surpassing classical computers. Companies like Quantinuum, IBM, and Infleqtion are rapidly advancing toward this goal, expecting to achieve it in the near future and signaling the true arrival of the quantum computing era.
