Perform easy multi-qubit parity measurements #13

Open sammorley-short opened 7 years ago

sammorley-short commented 7 years ago

It would be cool to have the native ability to perform parity measurements on qubits, e.g. make a X_1X_2 parity measurement on a Bell-state.

Program would, e.g. take a dictionary {node: pauli for node, pauli in parity_check} and perform the correct parity check.

Also, a way to perform a list of single qubit measurements that avoids doing: for node, pauli in measurements: gs.measure(node, pauli) but instead e.g. takes a dictionary of {node: pauli for node, pauli in measurements} and simply performs them sequentially.

Let's do it. I believe in your ability to write and submit the patch!

Since measurements need to be ordered, you probably want a list of tuples [(node, pauli), ...] rather than a dict. And the GraphState.parity_check method should probably re-use a generic GraphState.measure_sequence.

I managed the sequential measurement, but hadn't managed the multi-quint parity yet. Did you do this somewhere? I can't see a resolution to that?

Oh yeah ... please re-open!
