IBM will make 20-qubit quantum computing machine available as a cloud service by end of 2017 and unveils 50-qubit quantum computing prototype

Context & Ripple Effects
IBM's quantum program has been climbing a steady ladder of public access: in 2016 it opened a five-qubit machine as a free cloud service for students and researchers, and this announcement moves that same cloud-delivery model to a 20-qubit system while showing off a 50-qubit prototype behind it.
The significance is that IBM is treating qubit count as a published roadmap rather than a lab result — a cadence that continued with the 53-qubit machine opened for external use in 2019 and now runs all the way to the planned fault-tolerant IBM Quantum Starling targeted for 2029. Each step keeps IBM's hardware claims visible to the developer base its cloud service cultivates.
First-order effects
- Researchers and developers on IBM's cloud gain roughly four times the qubits of the 2016 five-qubit service, letting them run experiments that were previously out of reach without building their own hardware.
- The unveiled 50-qubit prototype signals to customers and rivals that IBM's next generation is already on the bench, not just on slides.
Second-order effects
- Rival quantum efforts face pressure to match IBM's cloud-access model, since free or cheap remote access is how IBM locks in the researcher community that will define early use cases.
- Cloud providers and enterprise buyers can begin budgeting for quantum as a rented resource alongside classical compute, shifting demand from bespoke lab installations toward platform subscriptions.
Third-order effects
- If the doubling cadence holds, quantum computing consolidates into a utility delivered over cloud platforms, with the eventual destination being fault-tolerant systems like the planned Starling rather than today's noisy prototypes.
- Whoever owns the access layer — as IBM does with its quantum cloud — accumulates the developer ecosystem and benchmark data that shape which algorithms and vendors matter when fault tolerance arrives.
The trend: Quantum computing is moving from laboratory hardware to cloud-delivered platforms, with IBM publishing a qubit-count roadmap that runs from the 2016 five-qubit service toward fault-tolerant machines.
