There is no confirmed date for quantum computers to become consumer products. IBM’s March 2026 roadmap targets a fault-tolerant system called Starling for client availability in 2029, but that is a company milestone—not a promised home-computer launch. For now, people can explore quantum computing remotely through cloud services rather than buy a quantum computer for home use.
Can you buy a quantum computer for home use today?
The sources available do not establish a consumer desktop quantum computer for sale. IBM describes its Quantum System Two systems as operating at IBM sites and partner centers, with specialized components including modular cryogenic infrastructure. Its current offering is access to quantum systems and tools through its platform, not ownership of a household appliance. See IBM’s quantum systems overview.
This distinction matters: a service that lets you submit jobs to a quantum processor is not the same as buying, installing, or possessing the processor.
What does IBM’s 2029 roadmap actually promise?
IBM’s Technology Atlas, updated in March 2026, says Starling is planned to be available to clients in 2029. IBM describes the planned fault-tolerant system as a modular, error-corrected quantum-centric supercomputer with 200 qubits capable of running 100 million gates. Those figures and the date are IBM’s goals, not an independently confirmed timetable for a consumer product. Read the IBM quantum roadmap.

IBM also states that its roadmap information represents current intent and is subject to change or withdrawal. The 2029 milestone should therefore be read as a target for client access, not a guaranteed launch date.
How can you try quantum computing now?
IBM offers cloud access through its Quantum Platform, including an Open Plan intended for learning and exploration. IBM’s product page lists up to 10 minutes of free runtime per month; its documentation describes the allowance as 10 minutes in a 28-day rolling window. Plan terms can change, so check the current IBM Quantum plans and Open Plan documentation before relying on the allowance.
As of March 16, 2026, IBM documentation also described an opt-in promotion providing eligible active Open Plan users with 180 additional minutes over the following 12 months. This is a time-limited promotion, not a permanent plan entitlement; confirm eligibility and terms in IBM’s live documentation.
- Choose your goal. Start with IBM’s learning material if you want to understand quantum-computing concepts; use the Open Plan if you want to explore cloud jobs.
- Use the platform remotely. Cloud access lets you submit work to IBM’s systems or use available simulators; it does not mean you own the hardware.
- Know what you are running on. IBM distinguishes physical quantum processing units (QPUs) from simulators and local testing. A simulated result is not a job run on a physical quantum processor.
For background reading, an introductory quantum-computing book can help explain the concepts, but a book is educational material—not a computer or a way to access quantum hardware.
