Authorizations

​
Authorization
string
header
required

API keys are associated with a user and can be created on the IonQ Quantum Cloud application. To authenticate, prefix your API Key with apiKey and place it in the Authorization request header. Ex: Authorization: apiKey your-api-key

Path Parameters

​
UUID
string<uuid>
required

A UUID identifying a specific resource

Response

200 - application/json

Successfully retrieved current characterization

Quantum hardware characterization data.

​
id
string<uuid>

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,
qpu.forte-enterprise-1
​
qubits
integer

The number of qubits available.

Required range: x >= 0
​
connectivity
integer[][]

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

Example:
[[0, 1], [0, 2], "...", [10, 9]]
​
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.
