The notion of a skyrmion as a topologically stable field configuration has proven to be highly versatile, manifesting in spintronics, condensed matter physics and more recently optics. Yet despite its origin in quantum field theory, skyrmions have only ever been observed as classical fields and particles. Here we report the first quantum skyrmion, existing as a non-local quantum entangled state that can be engineered and controlled through its wavefunction. We show that the topology of the quantum wavefunction makes this skyrmionic state robust to entanglement decay, remaining intact until the entanglement vanishes completely.
