In brief
A breakthrough announcement is a prompt to find the paper, the baseline and the error rate. It is not yet a result.

Separate the object from the adjective
Vendor research announcements use a stable set of words: breakthrough, advantage, commercial, scalable. None of those words is a measurement. The object is. Was it a physical qubit count, a logical qubit, an algorithm on a stated input size, a cryptographic implementation, or a partnership? Those are different stories. A count of physical qubits is a hardware component update. A standards-body algorithm is a software migration. A partnership is a press release until there is a system you can fail.
