Comparing the qubits on a chip
In the previous recipe, we looked at some of the pieces of information that you can glean about the IBM Quantum® hardware, illustrating the nature of today's NISQ machines. In this recipe, we will show a real comparison between the different qubits of a selected IBM backend.
We will run the same Bell state quantum program on three different setups: an ideal quantum computer (qasm_simulator), the best qubit pair, and the worst qubit pair on a 5-qubit, least busy IBM Quantum® machine.
We will print and plot the end result to compare the ideal result (
and 
at 50%) with the real results (a probabilistic mix of 
) to illustrate how today's quantum computers still have a little way to go.
