Appendix A: Overly Optimistic Claims of Quantum Computing
Disclaimer
All claims below are documented from public sources. Inclusion does not imply dishonesty — many were made in good faith. The pattern, however, is instructive.
| Year | Claimant | Claim | What Actually Happened |
|---|---|---|---|
| 2007 | Geordie Rose, D-Wave | "We've built the world's first commercial quantum computer" | Device was a quantum annealer; no evidence of quantum speedup over classical computers was established for years |
| 2011 | D-Wave / Lockheed Martin | Sale of D-Wave One implies commercial viability | System was used for research, not production; no commercial quantum advantage demonstrated |
| 2013 | Various | Google/NASA D-Wave purchase signals imminent breakthrough | Independent benchmarks showed no quantum speedup; debate continued for years about whether the device was truly quantum |
| 2017 | IBM | "In 5 years, quantum computing will be mainstream" | By 2022, IBM had revised its roadmap multiple times; no mainstream applications materialized |
| 2019 | Google / Hartmut Neven | "Quantum supremacy" achieved | Task had no commercial value; IBM showed a classical supercomputer could do it in 2.5 days, not 10,000 years |
| 2020 | Multiple startups | "Quantum advantage for drug discovery by 2023-2024" | No quantum advantage in drug discovery demonstrated as of 2025 |
| 2020 | IBM | Roadmap to 1,000+ qubits by 2023 and quantum advantage by 2025 | 1,121-qubit Condor chip built (2023) but with error rates too high for useful computation; quantum advantage not achieved |
| 2021 | IonQ (IPO filing) | "Broad quantum advantage" by 2025 | No broad quantum advantage demonstrated; stock declined significantly from IPO price |
| 2022 | McKinsey & Co. | Quantum computing could create \(450B-\)850B in value by 2035 | Based on optimistic assumptions about hardware progress that have not materialized |
| 2023 | Various VC firms | "Quantum computing is where AI was in 2012" | Misleading analogy: AI in 2012 had working hardware and clear commercial applications; quantum computing has neither |
