Used by branched simulation: when a mid-circuit measurement forks a path, each branch records its known outcome and replays the path’s instructions on a fresh simulation. Applying this op at replay time reproduces the correct post-measurement state for the branch, including the effect on qubits that were entangled with the measured one.
