Why Chinese funding figures are lower bounds

Most Chinese quantum financing is reported in RMB, often as a rounded phrase rather than an exact number. We publish a USD figure so the table can be sorted across regions. That conversion is a unit change, not a claim about purchasing power, and it is the first place a cross-region comparison can go wrong.

A phrase is not a number

Chinese technology media frequently report a round as 数亿元 or 近十亿元 — several hundred million RMB, or close to one billion — without giving a precise figure. We do not pick the middle of the range and present it as fact. Where a source gives only a phrase, the amount is recorded with an approximate flag, and in the ranking it is treated as a lower bound. Several rows consequently sit below what a reader might infer from the same headline.

This is a deliberate asymmetry. Overstating a Chinese row would be easy to do and impossible to defend; understating it produces a conservative table whose error is visible and documented. The original RMB string is kept in the dataset so anyone can apply their own conversion.

Conversion is a unit change, not an economic one

We convert at an approximate rate for the reporting period and keep the value in USD for comparability with the rest of the ledger. A Chinese page shows the same number in 亿美元, which is a Chinese unit for counting hundreds of millions of dollars — the currency does not change. We do not adjust for purchasing power, local cost structures or the fact that a domestic hardware round buys more engineering time in one market than another.

Anyone using this table to argue about relative national investment should read the regional-bias column first. The number answers a narrow question: how much cash was publicly reported, expressed in one unit. It does not answer how much capability that cash bought.

What the ~ marker commits us to

An amount with a ~ prefix is an approximation from public reporting, not a rounding convention applied for display. It can mean a converted RMB figure, a rounded headline number, or a total that includes an automatically detected round not yet verified. The methodology page defines each case; the company profile for that row states which caveat applies. No ~ figure is ever silently promoted to exact on a later build.

China-region rows currently published with a disclosed amount

10 rows in the current ledger match this column's classification. Each row keeps its source and instrument label.

The practical takeaway

If you cite a Chinese figure from this site, quote the ~ and the year. A reader who sees the rounded number without its qualifier will reasonably assume a precision we never claimed.
