Support multi-qubit measurements in deferred measurement transformer #5787
Conversation
There was a problem hiding this comment.
Are there any plans to provide a more explicit control on key conditions for a classically controlled operation? For example, can we say "Execute X(q0) only if measurement result of q1 and q0 is either both 0 or both 1" ? I guess this would require extending classically controlled operations to also accept control values?
It was a bit weird to see that the default strategy we are following for multi qubit classical controls is to activate the classical control on "anything but zeros". This can probably be a good first start, but I'm curious to hear if you've already thought on this.

A KeyCondition is triggered if it is non zero, which means at least one of the qubits it measured was non zero, which is equivalent to "anything but all zeros". To do more complex logic, you can use a SympyCondition . |

Use SumOfProducts to enable controls from multi-qubit measurements in deferred measurement transformer.
