QISKit(に基づくhello_quantum.py
)を使用して次の量子コードを取得しました。
import sys, os
from qiskit import QuantumProgram, QISKitError, RegisterSizeError
# Create a QuantumProgram object instance.
Q_program = QuantumProgram()
try:
import Qconfig
Q_program.set_api(Qconfig.APItoken, Qconfig.config["url"])
except:
offline = True
print("WARNING: There's no connection with IBMQuantumExperience servers.");
print("The backends available for use are: {}\n".format(",".join(Q_program.available_backends())))
backend = 'ibmqx5'
try:
# Create a Quantum Register called "qr" with 2 qubits.
qr = Q_program.create_quantum_register("qr", 2)
# Create a Classical Register called "cr" with 2 bits.
cr = Q_program.create_classical_register("cr", 2)
# Create a Quantum Circuit called "qc". involving the Quantum Register "qr"
# and the Classical Register "cr".
qc = Q_program.create_circuit("bell", [qr], [cr])
# Add the H gate in the Qubit 0, putting this qubit in superposition.
qc.h(qr[0])
# Add the CX gate on control qubit 0 and target qubit 1, putting
# the qubits in a Bell state
qc.cx(qr[0], qr[1])
# Add a Measure gate to see the state.
qc.measure(qr, cr)
# Compile and execute the Quantum Program.
result = Q_program.execute(["bell"], backend=backend, shots=1024, seed=1)
# Show the results.
print(result)
print(result.get_data("bell"))
except QISKitError as ex:
print('There was an error in the circuit!. Error = {}'.format(ex))
except RegisterSizeError as ex:
print('Error in the number of registers!. Error = {}'.format(ex))
私は自分APItoken
を次のQconfig.py
ように設定しました:
APItoken = 'XXX'
config = {
'url': 'https://quantumexperience.ng.bluemix.net/api',
}
ただし、コードは次のエラーで失敗します。
The backends available for use are: ibmqx2,ibmqx5,ibmqx4,ibmqx_hpc_qasm_simulator,ibmqx_qasm_simulator,local_qasm_simulator,local_clifford_simulator,local_qiskit_simulator,local_unitary_simulator
ERROR
There was an error in the circuit!. Error = 'QISkit Time Out'
私は両方をテストしたibmqx4
とibmqx5
、同じ問題を。/ qx / devicesでアクティブになっていることがわかります。
どういう意味ですか?IBM Qサーバーがダウンしているか、プログラムが大きすぎて実行できないのでしょうか?または何か他のことが起こっていますか?つまり、IBM量子サーバーで単純なHello Quantumプログラムを実行するにはどうすればよいですか?
