Path Parameters

backend
enum<string>
required

A backend where jobs can run on.

Available options:
qpu.harmony,
qpu.aria-1,
qpu.aria-2,
qpu.forte-1

Response

200 - application/json

Quantum hardware characterization data.

id
string

UUID of the characterization.

date
integer

Time of the measurement, from Unix epoch in seconds.

backend
enum<string>

The calibrated QPU being characterized.

Available options:
qpu.harmony,
qpu.aria-1,
qpu.aria-2,
qpu.forte-1
qubits
integer

The number of qubits available.

Required range: x > 0
connectivity
array

An array of valid, unordered tuples of possible qubits for executing two-qubit gates (e.g., [[0, 1], [0, 2], [1, 2]])

fidelity
object

Fidelity for single-qubit (1q) and two-qubit (2q) gates, and State Preparation and Measurement (spam) operations. Currently provides only mean fidelity; additional statistical data will be added in the future.

timing
object

Time, in seconds, of various system properties: t1 time, t2 time, 1q gate time, 2q gate time, readout time, and qubit reset time.
