And The Quantum Dragon’s Guide to Trimming It

Barron’s “How Quantum Computing Could Put IBM Back on Top Again” is paywalled, but you may be able to catch this gem near the top: “IBM has deployed 85 quantum systems to over 300 organizations, including 25 systems with more than 100 logical qubits, outpacing competitors like Google.” This information is partially corrected if you read the article in its entirety, but gee whiz that’s wrong.

IBM claims to have deployed 85 systems just to its cloud, not in total. 300+ organizations refers to the IBM Quantum Network, shortchanging IBM because systems on its “open” plan are accessible to everyone. The larger systems have 100+ physical qubits, not logical qubits. 25 might be right, but non-partners have only seen 15. Google has only deployed 2 to its cloud, so “outpaced” is a bit understated.
