What is quantum computing?
什麼是量子計算？
If you imagine a standard computer like a horse and cart, a quantum computer is more like a sports car – a huge leap forward.
如果你把一臺常規計算機想象成一架馬車，那麼量子計算機更像是一輛跑車——這是一項巨大的技術進步。
They appear to do similar jobs, but in fact, they are totally different.
常規計算機和量子計算機看似在完成相同的任務，但實際上它們完全不同。
Traditional computers store data in bits, which can be 1s or 0s.
傳統計算機存儲數據的最小單位是 “比特”，比特的值可以是 0 或 1。
They work by creating and storing long strings of many, many bits.
這些計算機通過創建和存儲由大量比特組成的許多長串數據來行使其功能。
But quantum computing’s ‘qubits’ can effectively be both at once.
但量子技術存儲數據的最小單位是 “量子比特”，它的值可以同時是 0 和 1。
This means that more data can be kept in fewer bits.
這意味著量子比特可以用更少的存儲單位存儲更多的數據。
So if this string on a regular computer represents a cat picture, in a quantum computer it might mean many things at once.
所以，如果常規計算機上的這串數據代表瞭一張貓的圖片，那麼在量子計算機上這串數據可以同時代表許多張圖片。
So with fewer qubits you can store much more information.
所以說，我們可以用更少的量子比特存儲更多的信息。
This means we can process information in a flash.
這就意味著我們可以在瞬間處理信息。
So it could speed up complex tasks like finding new drug molecules.
因此，量子計算機可以更快地完成復雜的任務，比如發現新的藥物分子。
But progress in quantum computing is slow.
但量子計算的發展非常緩慢。
The unpredictable and highly sensitive nature of qubits means it might be a long time until these machines are commonplace.
量子比特的不可預測性和高敏感性意味著距離量子計算機普及開來可能還有很長時間。
It’s unlikely that we’ll use quantum computers for everyday tasks.
我們可能並不會利用量子計算機完成日常工作。
But most experts say they will still be life-changing for everyone.
但大部分專傢都表示，量子計算將改變每一個人的生活。
