The IBM QX allows us to interface with IBM's remote quantum hardware and quantum simulation devices. We can execute code to simulate a quantum computer on our local machines, but it is good to have the option to run on IBM's simulation architecture or IBM's quantum computing hardware as we so choose. To do this, we will need an API key. Find the API key within the IBM QX menu under your account name called My Account (It should be in the upper right of the user interface). Click on Advanced, then Regenerate, and then on Copy API Token, to copy your API token. Insert this token into the Chapter 1 Jupyter Notebook and make note of it for future use, or come back to this section when you need it.
