IBM Quantum System Two price in 2026: what it costs to own one
"IBM Quantum System Two price" has no published answer: IBM sells the physical, on-premise system by direct enterprise and government contract, not from a price list. This page states that plainly, sets out what the system is, names the real installations that exist, breaks down what actually drives the cost of owning one, and gives the far cheaper cloud alternative with verified rates. For the transparent, per-minute cloud pricing on the same Heron processors, see the IBM Quantum pricing page; for physical machines you can price today, the quantum computer price list.
1.There is no list price
IBM does not publish a price for the Quantum System Two, and anyone quoting a precise figure is estimating. The system is sold on-premise under direct contract, scoped to the buyer's site: how many Heron processors, the cryogenic and shielding infrastructure, installation, facility upgrades, and multi-year support. Secondary industry coverage puts a complete on-premise IBM quantum installation into the millions of dollars, with estimates spanning roughly $3 million to $15 million or more depending on configuration. That is an industry-reported band, not an IBM list price, and the total cost of ownership runs higher once cryogenics, power, cooling and staff are added. This is the same reason D-Wave's commercial annealer and Google's Willow carry no public price.
2.What the System Two actually is
IBM Quantum System Two, first brought online at IBM's Poughkeepsie campus in December 2023, is IBM's modular quantum computer: a cryogenic architecture built to hold multiple quantum processors in one system and to scale toward the error-corrected machines on IBM's roadmap. Current installations run IBM's 156-qubit Heron r2 superconducting processor, which operates at about 99.7% two-qubit gate fidelity. Unlike the earlier System One, which houses a single processor, System Two is designed for extensibility, the hardware platform IBM intends to carry through its Nighthawk and error-corrected Starling generations. It is the physical counterpart to the cloud service: the same class of Heron QPU you reach over IBM's Pay-As-You-Go and Premium plans, but installed in your own building.
3.Who actually owns one
On-premise System Two installations are rare and named. The table below lists the confirmed deployments; each is a direct-contract placement, not a purchase from a list.
Table 1 — Confirmed IBM on-premise system installations, 2026
| Site | System | Source |
|---|---|---|
| RIKEN R-CCS, Kobe, Japan The first IBM Quantum System Two deployed outside the United States and outside an IBM data center. Co-located with the Fugaku supercomputer for quantum-centric supercomputing; launch ceremony 24 June 2025. | IBM Quantum System Two (156-qubit Heron) | verified primary |
| Cleveland Clinic, Ohio, USA The world's first quantum computer fully dedicated to healthcare research. In May 2026 the Cleveland Clinic-RIKEN-IBM team used up to 94 qubits and about 6,000 quantum operations to help simulate a 12,635-atom protein, the largest yet modelled with quantum computers. | IBM Quantum System One (Heron) | verified primary |
| IBM Quantum Data Center, Poughkeepsie, USA IBM's own utility-scale installation, where System Two was first brought online in December 2023 with three Heron processors. It anchors the roadmap toward Nighthawk and the error-corrected Starling era. | IBM Quantum System Two (multiple Heron QPUs) | verified primary |
Installations verified 2026-07-31 against IBM Newsroom, RIKEN and Cleveland Clinic releases. RIKEN's is the first IBM Quantum System Two outside the United States; the Cleveland Clinic runs a healthcare-dedicated System One.
4.What drives the cost of ownership
The purchase price, whatever it is negotiated at, is only part of the bill. A physical quantum system carries costs that a cloud subscription hides entirely: a dilution refrigerator and cryogenic plant to hold the qubits near absolute zero, electromagnetic and vibration shielding, the room and power and cooling to house it, installation and calibration, and a multi-year support and upgrade contract. Those recurring costs are why on-premise ownership is confined to national labs and large enterprise research programmes, and why the headline hardware figure understates the true total. For a buyer weighing it up, the honest comparison is not "system price versus cloud bill" but "system price plus facilities plus staff versus cloud bill."
5.The cheaper route: rent the same hardware
Unless you specifically need dedicated, always-on, on-site access, renting is cheaper by orders of magnitude and gives you the same Heron processors. IBM's Open Plan is free for 10 minutes of QPU runtime per 28-day window; Pay-As-You-Go is $96 per QPU-minute with no minimum; the Flex Plan is $72/minute against a $30,000 pre-purchase; Premium is an effective $48/minute on an annual contract. In other words, a small research project that would justify a multi-million-dollar System Two on paper can run on the cloud for tens of dollars.

6.Frequently asked questions
How much does an IBM Quantum System Two cost?
IBM does not publish a list price for the Quantum System Two. It is an on-premise system sold by direct enterprise or government contract, so the price depends on configuration, the number of Heron processors, support terms and the buyer's own facility work. Secondary industry coverage puts a complete on-premise IBM quantum installation into the millions of dollars, with estimates spanning roughly $3 million to $15 million or more depending on scale. Because IBM quotes privately, treat any single headline number, including that range, as an estimate rather than a published price.
Can you buy an IBM Quantum System Two?
Yes, but not off a price list. IBM installs System Two on-premise for a small number of enterprise, research and government customers under direct contract, RIKEN in Japan and IBM's own Poughkeepsie data center among them. There is no add-to-cart price: you engage IBM directly, and the deal is scoped to your site, power, cooling and support needs. For everyone else, IBM sells access to the same Heron hardware over the cloud instead of the physical system.
What is the difference between IBM Quantum System One and System Two?
System One (2019) is IBM's first self-contained commercial quantum system, housing a single processor; installations include the Cleveland Clinic's healthcare-dedicated machine. System Two (first online December 2023) is the newer modular architecture, designed to hold multiple processors in one cryogenic infrastructure and to scale toward IBM's error-corrected roadmap. RIKEN's System Two, co-located with the Fugaku supercomputer, runs a 156-qubit Heron processor. Neither system has a public list price; both are sold by direct contract.
Why doesn't IBM publish a price for its quantum computers?
A physical quantum system is not a catalogue product. The cost is dominated by things that vary per buyer: how many Heron processors, the dilution-refrigerator and cryogenic plant, electromagnetic shielding and facility upgrades, installation, and multi-year support. IBM scopes each on-premise deal individually, so it quotes rather than lists. This is the same reason D-Wave's commercial annealer and Google's Willow carry no public price either. What IBM does publish is its cloud pricing, where the per-minute rates are transparent.
Is it cheaper to rent IBM quantum access than to buy a system?
For almost everyone, yes, by many orders of magnitude. Buying a System Two means a multi-million-dollar capital project plus the cryogenic infrastructure and staff to run it. Renting the same Heron hardware over IBM's cloud costs nothing on the free Open Plan (10 minutes of QPU runtime per 28-day window) and $96 per QPU-minute on Pay-As-You-Go above that. Buying only makes sense when you need dedicated, always-on, on-site access, typically a national lab or a large enterprise research programme, and can absorb both the purchase and the running cost.
