In this talk, I present recent results on the first experimental observation of non-local magic in a superconducting quantum processing unit (QPU). Magic, also known as non-stabilizerness, is a fundamental non-classical resource that enables universal quantum computation beyond the Clifford paradigm. Understanding how magic is generated, distributed, and erased is essential for the development of efficient and scalable fault-tolerant quantum computers. Quantum advantage arises only when both entanglement and magic coexist; yet, entanglement can also enhance magic as a resource. Non-local magic is impervious to local unitary operations and is catalysed by entanglement. Direct access to the UniNA quantum hardware enables us to identify and characterize the dominant noise mechanisms intrinsic to the QPU device. We find excellent agreement between theory and experiment without introducing any free parameters in the noise model. Leveraging this explicit knowledge of noise channels, we establish a systematic framework to isolate and quantify non-local magic in realistic quantum devices.
