English(EN) Quantum computers can get colder than deep space — Here's how they stay running

量子计算机的运行温度比深空还低，以保护量子比特

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-25 13:30

量子计算机需要极低的温度，远低于深空温度，以维持量子比特的脆弱状态。IBM最新的低温系统实现了低于15毫开尔文的温度，比深空温度低180多倍，以最大限度地减少热引起的退相干。这种极低的温度至关重要，因为任何外部能量都可能扰乱量子比特的量子态，导致计算不准确。虽然稀释制冷机很常见，但中性原子机等替代方法使用激光将原子冷却到微开尔文温度，从而绕过了一些与传统低温冷却相关的挑战。 AI

影响确保量子计算的稳定性和准确性，这对于未来AI的进步至关重要。

Signal score: 32 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; 讨论了量子计算机运行的技术要求和方法，包括低温冷却。[lever_c_demoted from research: ic=1 ai=0.7]
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: infra; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: High; Clearly on-topic for AI-industry coverage.
Story freshness: Breaking (< 6h); Fresh story with cross-source coverage still developing. Ranking may shift as more sources report.

Quantum computers can get colder than deep space — Here's how they stay running

Heat disrupts the accuracy of a quantum computer, so the computer needs to be kept as cold as possible. Which is extremely cold, it turns out.
