On Construction of Approximate Real Mutually Unbiased Bases for an infinite class of dimensions $d\not\equiv 0\mathrm{mod}4$

Ajeet Kumar, Rakesh Kumar, Subhamoy Maitra +1

It is known that real Mutually Unbiased Bases (MUBs) do not exist for any dimension $d>2$ which is not divisible by 4. Thus, the next combinatorial question is how one can constr…
