Define models needed for command line script

[dexter2206]

We agreed that the command line script will accept YAML files as inputs and produce a YAML string as output. The validation of inputs and outputs, as well as serialization/deserialization, will be handled by pydantic.

We need to define the following models:

• model describing the experiment (currently only Fourier-discrimination)
• model describing the device used
• model describing the output
  • this one should include information defining the experiment and the device used so that the results files are self-contained

The examples below demonstrate suggested valid instances of the models written in YAML format, although the precise details of models may be changed at the discretion of the implementer.

Experiment

type: fourier_discrimination,
qubits: 
- target: 0
  ancilla: 1
- target: 5
  ancilla: 2
angle: 
  start: 0.1
  stop: 0.2 
  number_of_steps: 2
method: postselection
number_of_shots: 5

Device description

arn: arn:aws:braket:eu-west-2::device/qpu/oqc/Lucy
disable_qubit_rewiring: true
gateset: lucy
