Dense Coding with Locality Restriction on Decoders: Quantum Encoders versus Superquantum Encoders
We investigate practical dense coding by imposing locality restrictions on decoders and symmetry restrictions on encoders within the resource theory of asymmetry framework. In this task, the sender Alice and the helper Fred preshare an entangled state. Alice encodes a classical message into the quan...
