Authorizations

Authorization
string
headerrequired

We provide API keys to govern access—we'll provision your account with one key, and more can be provided upon request.

Every key is fully privileged within the system, and should be kept private.

To authenticate, prefix your API Key with apiKey and place it in the Authorization request header. For example: Authorization: apiKey your-api-key

Path Parameters

backend
enum<string>
required

A backend where jobs can run on.

Available options:
qpu.s11

Response

200 - application/json
id
string

UUID of the characterization.

date
integer

Time of the measurement, from Unix epoch in seconds.

target
enum<string>

The target calibrated hardware.

Available options:
qpu.s11
qubits
integer

The number of qubits available.

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.
