What Quantum Washing Is

I first wrote about quantum snake oil in 2001, when a startup was marketing “neural quantum encryption” that turned out to be rebranded XOR. Twenty-five years later, the problem has not merely survived. It has industrialized.

Quantum washing is the practice of attaching the word “quantum” to a product, service, company, or claim to borrow scientific credibility that the underlying offering has not earned. The label covers a spectrum. At the mild end, a cybersecurity vendor adds “quantum-safe” to a product description without implementing any post-quantum algorithm. At the severe end, a publicly traded company fabricates a quantum chip foundry, invents revenue from sham transactions, and inflates NASA partnerships to pump its stock price.

The term follows the same linguistic template as greenwashing (exaggerating environmental credentials) and AI washing (exaggerating artificial intelligence capabilities). The mechanism is identical in all three cases: a company attaches a high-value adjective to a product, exploits the gap between public enthusiasm and public understanding, and profits from the confusion before anyone asks what the adjective actually means.

What makes quantum washing harder to police than its predecessors is the evaluation gap. Most executives, investors, and journalists can form a rough judgment about whether a product is “green” or “AI-powered.” Almost none of them can evaluate whether a product is “quantum” in any meaningful sense. The physics is hard, the terminology is unfamiliar, and the field changes fast enough that even informed observers someti…
