Quantum Secret Sharing and Error Correction vs No-Cloning
A new arXiv preprint looks at how the no-cloning theorem constrains quantum secret sharing. It points out that access structures which are easy to realise classically can be ruled out once the shared secret is quantum. The abstract suggests no-cloning may exactly mark the boundary between attainable and unattainable quantum access structures.

A precise link between no-cloning and quantum access structures could allow protocol designers to rule out impossible quantum secret sharing schemes before implementation, reducing trial and error in early quantum networks.
If the mathematical characterisation is complete, feasibility checks become a design-time step rather than an experimental discovery, which could be applied immediately to planned multipartite quantum communication systems.
