What is quantum computing?

什么是量子计算？

If you imagine a standard computer like a horse and cart, a quantum computer is more like a sports car – a huge leap forward.

如果你把一台常规计算机想象成一架马车，那么量子计算机更像是一辆跑车——这是一项巨大的技术进步。

They appear to do similar jobs, but in fact, they are totally different.

常规计算机和量子计算机看似在完成相同的任务，但实际上它们完全不同。

Traditional computers store data in bits, which can be 1s or 0s.

传统计算机存储数据的最小单位是 “比特”，比特的值可以是 0 或 1。

They work by creating and storing long strings of many, many bits.

这些计算机通过创建和存储由大量比特组成的许多长串数据来行使其功能。

But quantum computing's 'qubits' can effectively be both at once.

但量子技术存储数据的最小单位是 “量子比特”，它的值可以同时是 0 和 1。

This means that more data can be kept in fewer bits.

这意味着量子比特可以用更少的存储单位存储更多的数据。

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，如果常规计算机上的这串数据代表了一张猫的图片，那么在量子计算机上这串数据可以同时代表许多张图片。

So with fewer qubits you can store much more information.

所以说，我们可以用更少的量子比特存储更多的信息。

This means we can process information in a flash.

这就意味着我们可以在瞬间处理信息。

So it could speed up complex tasks like finding new drug molecules.

因此，量子计算机可以更快地完成复杂的任务，比如发现新的药物分子。

But progress in quantum computing is slow.

但量子计算的发展非常缓慢。

The unpredictable and highly sensitive nature of qubits means it might be a long time until these machines are commonplace.

量子比特的不可预测性和高敏感性意味着距离量子计算机普及开来可能还有很长时间。

It's unlikely that we'll use quantum computers for everyday tasks.

我们可能并不会利用量子计算机完成日常工作。

But most experts say they will still be life-changing for everyone.

但大部分专家都表示，量子计算将改变每一个人的生活。
