Quickstart

pip install purplecaffeine

from qiskit.circuit.random import random_circuit
from qiskit.quantum_info.random import random_pauli
from qiskit.primitives import Estimator

from purplecaffeine.core import Trial, LocalStorage
from purplecaffeine.widget import Widget

n_qubits = 4
depth = 3
shots = 2000

circuit = random_circuit(n_qubits, depth)
obs = random_pauli(n_qubits)

local_storage = LocalStorage("./trials")

with Trial("Example trial", storage=local_storage) as trial:
    # track some parameters
    trial.add_parameter("estimator", "qiskit.primitives.Estimator")
    trial.add_parameter("depth", depth)
    trial.add_parameter("n_qubits", n_qubits)
    trial.add_parameter("shots", shots)
    
    # track objects of interest
    trial.add_circuit("circuit", circuit)
    trial.add_operator("obs", obs)

    # run
    exp_value = Estimator().run(circuit, obs, shots=shots).result().values.item()
    
    # track results of run
    trial.add_metric("exp_value", exp_value)

Widget(local_storage).show()
