PHYS2111 Quantum Mechanics -- Lecture 13 Part 2

This lecture is on the basics of quantum computation. We take a more computational approach to the subject in this second half by using the Qiskit package for Jupyter Notebooks to program up a basic quantum circuit and run it on IBM Quantum's public access quantum computer. The circuit we look at is very simple, 3 qubits, a Hadamard gate and two CNOT gates to generate the Greenburger-Horne-Zeilinger (GHZ) state, which is the 3-qubit equivalent of the triplet-plus state, and then measure it to 3 classical bit lines. We work through the full code sequence for this, as something of a 'hello world' introduction to quantum computer programming that people can extend upon.

System details: Running Jupyter Notebook on PC via Anaconda 3 install, with Qiskit, Numpy and Matplotlib as required packages. Happy to share my two Jupyter Notebook files for this by request.
