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 …

Stochastic behavior of outcome of Schur-Weyl duality measurement
We focus on the measurement defined by the decomposition based on Schur-Weyl duality
on $ n $ qubits. As the first setting, we discuss the asymptotic behavior of the measurement …
