I want to run the circuit given below, but I am getting the following error.
QiskitError: "Cannot unroll the circuit to the given basis, ['u1', 'u2', 'u3', 'cx', 'id', 'unitary']. Instruction cphi_0 not found in equivalence library and no rule found to expand."
Why do you think I am encountering this error? I am sharing the codes below. What should I do to run the circuit?
from qiskit_quantum_knn.qknn.qknn_construction import create_oracle, initialise_qknn, state_transformation, add_measurements
from qiskit import BasicAer, execute
n_dim_qubits = 1 # must be log(len(test_state))
n_samps_qubits = 1 # must be log(len(train_data))
test_state = [0, 1]
train_data = [
[1, 0],
[0, 1]
]
oracle = create_oracle(train_data)
init_circ = initialise_qknn(n_dim_qubits, n_samps_qubits, test_state)
state_circ = state_transformation(init_circ, oracle)
final_circ = add_measurements(state_circ)
display(final_circ.draw(output="mpl"))
backend = BasicAer.get_backend('qasm_simulator')
job = execute(final_circ, backend, shots=1024)
