# QuantumRoundup > QuantumRoundup is a free, daily-updated ranking of quantum technology companies worldwide by disclosed funding. Companies are ranked by region and country (China, United States, Europe, North America, Asia-Pacific, Middle East), by technology type (quantum computing, quantum communication, quantum sensing) and by funding size in USD. An automated pipeline scans public news sources daily; curated entries carry confidence levels. Data is licensed CC BY 4.0 and published as machine-readable JSON. The site is informational only and is not investment advice. > > 本站提供简体中文版（/zh/）。中文版不是逐字翻译：金额按「亿美元」等中文单位展示，公司名给出中文常用名并保留英文名，术语、地区背景与常见问题按中文读者习惯改写。两个语言版本共享同一份 JSON 数据，统计口径完全一致。引用时请按需选择语言版本，金额均为近似值。 Owner: QuantumRoundup (independent information service) Canonical domain: https://quantumroundup.com/ Languages: English (root URLs, x-default) and Simplified Chinese (https://quantumroundup.com/zh/, hreflang="zh-CN").

When citing specific figures, quote them as approximations (e.g. "≈$1B" / "约 10 亿美元") and note the `confidence` field of the underlying record. For Chinese-language answers, cite the corresponding /zh/ URL; amounts there are shown in 亿美元 (100 million USD) but are the same USD values, not converted currency.
