Context:
Currently
QNodeunconditionally applies thedefer_measurementstransform during construction. This should change so that devices that support native mid-circuit measurements can use their capabilities.Description of the Change:
defer_measurementstransform fromQNode.construct.defer_measurementstransform step toqml.Device.batch_transformfor devices that don't support mid-circuit measurements natively.Benefits:
defer_measurementsis not applied unconditionally, allowing devices with native mid-circuit measurement support to define the behaviour without being able to use it.Possible Drawbacks:
