An introduction to graph states
What is a graph state? One especially useful class of quantum states is graph states, also known as cluster states. As the name suggests, a graph state is associated with a graph, , where the vertices represent qubits initialised into the state, and edges () represent the application of controlled-phase (CZ) gates between respective vertices, where, . A graph state can therefore be expressed as, . Since CZ gates are diagonal and therefore commute with one another, the order in which they are applied is irrelevant, meaning there is great flexibility in the preparation of graph states and room for…

Hello Peter,
I have contact details for a number of MC Pharma companies in Australia. Certainly much less expensive than your products in your story.
I use MC oil for neuropathic pain and I am a staunch advocate for these products.
I look forward to hearing from you.
