State Tomographies

Parameters

class qibocal.protocols.state_tomography.StateTomographyParameters(circuit: Optional[Union[str, Circuit]] = None)

Tomography input parameters

circuit: Optional[Union[str, Circuit]] = None

Circuit to prepare initial state.

It can also be provided the path to a json file containing a serialized circuit.

hardware_average: bool = False

By default hardware average will be performed.

nshots: int

Number of executions on hardware.

relaxation_time: float

Wait time for the qubit to decohere back to the gnd state.

Example

Below is an example runcard for this experiment.

- id: state_tomography
  operation: state_tomography
  parameters:
    nshots: 1024
    relaxation_time: 200000

The expected output is the following:

Qibocal also provides two qubit state tomography.

- id: tomography
  operation: two_qubit_state_tomography
  parameters:
    nshots: 5000

The report will look like the following.
