How-to: run circuit on Braket local backend

This notebook demonstrates running a quantum circuit on the local Braket backend using the Qiskit Braket Provider. It shows the process of defining the backend, creating a simple quantum circuit, running the circuit, and retrieving results.

First let’s create a circuit for a Bell state.

from qiskit import QuantumCircuit
from qiskit.visualization import plot_histogram, plot_state_city
from qiskit_braket_provider import BraketLocalBackend

# Create a Local Backend
backend = BraketLocalBackend(name="default")

# Create a simple circuit
circuit = QuantumCircuit(2)
circuit.h(0)
circuit.cx(0, 1)

<qiskit.circuit.instructionset.InstructionSet at 0x7f6866f51bb0>

Then we can run the circuit for shots times like we do in AWS backends: the difference is that the simulation is running on your computer.

result = backend.run(circuit, shots=2000).result()
plot_histogram(result.get_counts())

Setting shots=0 we are able to get the exact resulting state vector.

result = backend.run(circuit, shots=0).result()
plot_state_city(result.get_statevector())
