   What changed

   Current access

   Previously

   Open and paid cloud plans: IBM documents Heron r2 access on Open Plan. Its September 2026 changelog adds Nighthawk r2 ibm_phoenix for Premium, Flex and Pay-As-You-Go; access and supported instructions depend on the selected backend.

   Now

   Open and paid cloud plans: IBM Quantum Platform offers Open and paid plans. The Open Plan documentation specifies the resource-unit equivalent of up to 10 QPU minutes per rolling 28-day window, with Open instances created in the us-east region. Available backends and advanced features depend on the plan.
