Google Quantum Ai Plans Pricing
Access to the Google Quantum Engine API is not commercially metered. There is no public price list, no per-shot fee, and no per-second processor charge. Access is gated by: 1. A Google Cloud project with the Quantum Computing API enabled and billing attached (no billable Quantum Engine SKU appears today — billing is required only to keep the project active). 2. A Google sponsor adding the user to the approved list. 3. For the latest hardware, acceptance into the Willow Early Access Program (proposal-based). All Google Quantum AI open-source software (Cirq, qsim, OpenFermion, Stim, Qualtran, ReCirq, Tesseract, Unitary) is distributed free under the Apache 2.0 licence.
Google Quantum Ai Plans Pricing is the machine-readable pricing-plan profile for Google Quantum AI on the APIs.io network, conforming to the API Commons Plans specification.
It defines 3 plans, covering free, approval-based, and program tiers, with named plans including Open Source Software, Quantum Engine (Approved Access), Willow Early Access Program.
Tagged areas include Quantum Computing, Quantum Engine, Willow, Sycamore, and Sponsored Access.
