Abstract:
We study mutually unbiased bases (MUBs) in which all the bases are unextendible maximally entangled ones. We first present a necessary and sufficient condition of constructing a pair of MUBs in C2 C4. Based on this condition, an analytical necessary condition for constructing MUBs is given. Moreover we illustrate our approach by some detailed examples in C2 C4. The results are generalized to C2 Cd (d 3) and a concrete example in C2 C8 is given.
