Coding the teleportation circuitry

In this section, we will provide code to teleport qubits and test the results. We’ve divided the code into three parts:

• Creating registers
• Adding gates to the registers
• Running the quantum circuit

Creating registers

We start with the imports:

from qiskit import QuantumCircuit, QuantumRegister, \    ClassicalRegister, Aer
import random
import numpy as np
from qiskit.result import marginal_counts

In this chapter, the only new import is marginal_counts. We will describe that function later in this section.

The following function defines a circuit:

def create_registers():    alice_q = QuantumRegister(1, 'alice (q)')
    peter_alice_q = \
        QuantumRegister(1, 'peter/alice (q)')
    peter_bob_q = QuantumRegister(1, 'peter/bob (q)')
    ...
