Butson-type complex Hadamard matrices and association schemes on Galois rings of characteristic 4
Takuya Ikuta, Akihiro Munemasa
We consider nonsymmetric hermitian complex Hadamard matrices belonging to the Bose-Mesner algebra of commutative nonsymmetric association schemes. First, we give a characterization…

Implementation of quantum state tomography for time-bin qudits
Takuya Ikuta, Hiroki Takesue
Quantum state tomography (QST) is an essential tool for characterizing an unknown quantum state. Recently, QST has been performed for entangled qudits based on orbital angular mome…
