Python QueuingContext.remove Examples

Example #1

File: operation_recorder.py Project: ldabas/QuantumResearch

    def _process_queue(self):
        super()._process_queue()

        for obj, info in self._queue.items():
            QueuingContext.append(obj, **info)

        # remove the operation recorder from the queuing
        # context
        QueuingContext.remove(self)

        new_tape = self.expand(depth=5, stop_at=lambda obj: not isinstance(obj, QuantumTape))
        self.ops = new_tape.operations
        self.obs = new_tape.observables

Example #2

File: test_queuing.py Project: wongwsvincent/pennylane

    def test_remove_no_context(self):
        """Test that remove does not fail when no context is present."""

        QueuingContext.remove(qml.PauliZ(0))
