“…Mutually unbiased bases (MUBs), first introduced by Schwinger, [1] have many important applications in the field of quantum information theory; for instance, Bell inequalities, [2] quantum key distribution protocols, [3] quantum state tomography, [4] and non-Gaussianity of quantum states in quantum optics communities. [5] A complete set of MUBs can be used to construct an optimal scheme of orthogonal quantum measurement for the quantum system.…”
