Installation

To install,

pip install oqd-analog-emulator

or

pip install git+https://github.com/OpenQuantumDesign/oqd-analog-emulator.git

To clone the repository locally for development:

git clone https://github.com/OpenQuantumDesign/oqd-analog-emulator.git
pip install .

This OQD repository depends on the oqd-core and oqd-compiler-infrastructure packages, which should be installed with all other dependencies. If needed, these can be manually installed via,

pip install oqd-compiler-infrastructure
pip install oqd-core

Getting Started

For example, to simulate a simple Rabi flopping experiment:

import matplotlib.pyplot as plt

from oqd_core.interface.analog.operator import *
from oqd_core.interface.analog.operation import *
from oqd_core.backend.metric import *
from oqd_core.backend.task import Task, TaskArgsAnalog
from oqd_analog_emulator.qutip_backend import QutipBackend

X = PauliX()
Z = PauliZ()

circuit = AnalogCircuit()
circuit.evolve(duration=10, gate=AnalogGate(hamiltonian=X))

args = TaskArgsAnalog(
    n_shots=100,
    fock_cutoff=4,
    metrics={"Z": Expectation(operator=Z)},
    dt=1e-3,
)

task = Task(program=circuit, args=args)

backend = QutipBackend()
results = backend.run(task=task)

plt.plot(results.times, results.metrics["Z"], label=f"$\\langle Z \\rangle$")
