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
