Reported evidence
What the sources report
A balance sheet describes assets and obligations at a point in time. Income and cash-flow statements describe activity over a period. A cash balance and annual revenue therefore answer different questions.
IBM distinguishes storing protected quantum information from carrying out a computation. Its architecture discussion requires logical operations, error decoding and a system that can scale; memory alone is insufficient.
NIST's finalized post-quantum standards concern cryptographic protection against future quantum attacks. Their deployment is a different activity from manufacturing quantum processors.
Our interpretation
Investor relevance — interpretation
For each company, write down the customer, what is sold and which part of the revenue is actually disclosed. If a diversified company does not isolate quantum revenue, mark that exposure unknown instead of assigning its entire revenue to quantum computing.
Translate a scientific announcement into an evidence question: what task ran, what was measured, which classical alternative was tested, and what still needs to work? Then ask whether the result changes a product, a customer contract or a financial estimate. These are separate steps.
Build a research sheet with the reporting period, revenue, operating cash flow, cash versus investments, financing obligations and share-count changes. Record management targets separately from reported outcomes. Return to the source when a headline collapses these distinctions.
Keep hardware, software access, sensing, networking and quantum-resistant cryptography separately labeled. A broad quantum theme is not a uniform business model.
Our interpretation
What this does not establish
This checklist provides education, not a valuation, portfolio allocation or recommendation. It does not estimate investment returns or verify any company's current financial position.
The IBM source is an issuer explanation and roadmap. Its future delivery promises must not be treated as independently established performance.
