Updated Doing Nothing with Qiskit

In this notebook, we demonstrate how to create and execute a quantum circuit using Qiskit. This updated code works with the latest version of Qiskit, addressing previous issues with deprecated functions and imports.

Importing Necessary Libraries

First, we need to import the required libraries:

In [39]:

import qiskit
import qiskit_aer

Creating Quantum and Classical Registers

We create a quantum register with 1 qubit and a classical register with 1 bit to store measurement results:

In [40]:

qr = qiskit.QuantumRegister(1)
cr = qiskit.ClassicalRegister(1)
program = qiskit.QuantumCircuit(qr, cr)

Defining the Quantum Circuit

Next, we define the quantum circuit and add a measurement operation:

In [41]:

program.measure(qr, cr)

Out[41]:

<qiskit.circuit.instructionset.InstructionSet at 0x1f13fe2f100>

Selecting the Backend and Transpiling the Circuit

We choose the qasm_simulator backend from Aer for simulation. The circuit is then transpiled to be compatible with this backend:

In [42]:

backend = qiskit_aer.Aer.get_backend('qasm_simulator')
program_ = qiskit.transpile(program, backend)
job = backend.run(program_)

Running the Circuit and Retrieving Results

Finally, we run the transpiled circuit on the simulator and print the results:

In [43]:

result = job.result()
counts = result.get_counts()
print(counts)

{'0': 1024}

Great! Now you are ready to create and execute programs!
