Machines

Machine properties

The backend's real capabilities for compiling against it — native gate set, accepted gates (the server transpiles down), shot range, connectivity class — without a coupling map or anything else that would fingerprint the upstream vendor of a white-labeled machine.

Auth: HTTP bearer

Path parameters

idstring required

Example:roro.sim.sv

The machine's targetId (codename).

Response

The machine's properties

targetIdstring

displayNamestring

providerstring

As in Machine.provider.

kind'sim' | 'qpu'

type'aer' | 'qsimulator' | 'qtester' | 'qpu'

qubitsinteger

nativeGatesstring[]

What the hardware physically executes.

acceptedGatesstring[]

What the API accepts for this machine — the server transpiles the rest.

connectivity'all-to-all' | 'nearest-neighbour' | 'programmable' | 'limited'

minShotsinteger

The smallest shot count this backend accepts.

maxShotsinteger

The largest shot count this backend accepts.

modality'simulator' | 'superconducting' | 'trapped-ion' | 'neutral-atom'

availabilitystring

analogboolean

resiliencestring[]

Error-mitigation methods a run on this machine may request right now (resilience on a run). Empty when none — resilienceNote says why.

resilienceNotestring

Why nothing is offered (e.g. an exact simulator has no readout error to mitigate), or a note on what is (e.g. a layout hint is advisory). Empty when there is nothing to add.

resilienceState'offered' | 'switched-off-by-operator' | 'not-offered'

offered; switched-off-by-operator (available on this class of machine, switched off right now); not-offered (does not apply here).

resilienceMaxEffectiveShotsinteger nullable

The most shot-equivalents one resilience run may bill here; null when nothing is offered.

priceModel'free' | 'per-shot' | 'per-second' | 'per-job'

How this machine prices a run: free (RoRo's own simulators), per-shot (every rate below is 0), per-second (a rate per projected quantum-second, usually with a per-job minimum), or per-job (a job fee or minimum on top of the per-shot rate). These are RATES; what a run costs is what POST /v1/runs/quote answers.

costPerSecondnumber double

Credits per projected quantum-second (0 when the machine has no time rate).

costPerJobnumber double

Credits added to every job (0 when none).

minJobCreditsnumber double

The least a job costs, in credits (0 when there is no floor).
