But if you want a million spin qubits, you just put it on a standard 300 millimeter silicon wafer. You run it through the exact same photolithography machines at TSMC, ASML, Intel.

但如果你想要一百万个自旋量子比特，你只需把它放在标准的 300 毫米硅晶圆上，用 TSMC、ASML、Intel 的同一套光刻机跑一遍。

A quantum computer is not a machine that tries every single answer at the same time because a qubit is a zero and a one simultaneously.

量子计算机不是一台同时尝试所有答案的机器，因为一个量子比特同时是 0 和 1。

This is where the startup pitch decks collide with reality. They collide with the laws of thermodynamics and the laws of economics, which are not real laws, which is why the economics Nobel Prize is not a real Nobel Prize.

这是创业公司宣传材料与现实碰撞的地方。它们与热力学定律和经济学定律碰撞，而经济学定律并不是真正的定律，这就是为什么经济学诺贝尔奖不是真正的诺贝尔奖。

For a thousand plus logical qubits. Which is not the million we talked about earlier. No. It's just a thousand. Thousand logical qubits. You need 10 million physical qubits of these transplants.

对于一千多个逻辑量子比特。这不是我们之前谈到的百万。不，只是一千。一千个逻辑量子比特。你需要一千万个这些 transmon 物理量子比特。

Here, even if we achieve scale, because the gate times are so slow, it might take like on the order of a year to decrypt 2048 RSA.

在这里，即使我们实现了规模化，由于门时间太慢，破解 2048 位 RSA 可能需要大约一年的时间。

the current evidence is not enough. And you need to show, like, you know, I would expect, for example, a statistical analysis of valley splitting across devices.

目前的证据不足。你需要展示，比如，我期望看到跨器件的谷分裂统计分析。

I don't think it's going to be the future quantum computer. You know, once it's achieved, I think silicon is going to be the one that actually gets scaled because it's cheap and it's easy to make.

我不认为它会成为未来的量子计算机。你知道，一旦实现，我认为硅将是真正被规模化的那一个，因为它便宜且容易制造。

术语

transmon超导量子比特的一种

用约瑟夫森结引入非谐性，使能级不等距，避免误操作。

valley splitting谷分裂

硅中电子多个能谷的简并被解除后的能级差，决定硅自旋量子比特质量。

2DEG二维电子气

将电子限制在平面内运动，是硅量子点的物理基础。

DETR检测变换器

目标检测模型，此处用于识别调谐图像中的隧穿条纹。

exchange-only qubit仅交换作用量子比特

只用电子间交换作用就能实现量子门，无需微波，但每个比特需三个电子。
