Honeywell unveils Model H1, a quantum computer with 10 qubits reaching a quantum volume of 128, offered along with a subscription service for usage
Honeywell, which was a bit of a surprise entrant into the quantum computing space when it announced its efforts to build the world's …
Context & Ripple Effects
Honeywell entered quantum computing in March 2020 with a promise to ship a machine within three months and a claim of at least a quantum volume of 64, then the world's most powerful. The Model H1 delivers on that arc eight months later, doubling the benchmark to 128 — notable because Honeywell is competing on quantum volume rather than raw qubit count, against rivals like D-Wave whose 2000Q machine packed 2000 qubits at a $15M price tag.
The subscription model matters as much as the hardware: rather than selling a $15M box, Honeywell rents usage access, echoing the cloud path Microsoft laid out when it announced [[a:947545|Azure Quantum would give select customers access to prototype machines from Honeywell, IonQ, and QCI]]. This is also the business that later becomes Quantinuum via the Cambridge Quantum joint venture, which Honeywell still majority-owns.
First-order effects
- Honeywell converts its March promise into a shipping product with double the claimed quantum volume, giving it a concrete benchmark lead over D-Wave's qubit-heavy approach.
- Subscription access means enterprise customers and Azure Quantum users can buy quantum compute as an operating expense instead of a capital purchase, widening the buyer pool beyond national labs and deep-pocketed corporates.
Second-order effects
- Competitors are pushed to argue benchmarks: if quantum volume becomes the headline metric buyers track, qubit-count marketing like D-Wave's loses pricing power, and every vendor must publish comparable quality figures.
- Cloud intermediaries gain leverage — Microsoft's Azure Quantum aggregates access across Honeywell, IonQ, and QCI, so subscription-priced machines strengthen the broker position between quantum hardware makers and end users.
Third-order effects
- If usage-based access holds as the dominant commercial model, quantum computing consolidates around a few platform owners — a structure that culminates in Honeywell folding this business into Quantinuum and reportedly weighing a US IPO at roughly a $10B valuation, making quantum a standalone asset class rather than a corporate lab project.
- Benchmark competition shifts industry accounting from hardware sales to measured computational quality per dollar, forcing regulators and enterprise buyers to eventually standardize how quantum performance claims are verified.
The trend: Quantum computing is moving from bespoke million-dollar machines sold on qubit counts toward subscription-accessed platforms judged on quality metrics like quantum volume — a shift that turns hardware makers into service businesses and sets up standalone vehicles like Quantinuum.
