On Construction of Approximate Real Mutually Unbiased Bases for an infinite class of dimensions
Ajeet Kumar, Rakesh Kumar, Subhamoy Maitra +1
It is known that real Mutually Unbiased Bases (MUBs) do not exist for any dimension which is not divisible by 4. Thus, the next combinatorial question is how one can constr…
On Obtaining New MUBs by Finding Points on Complete Intersection Varieties over
Arindam Banerjee, Kanoy Kumar Das, Ajeet Kumar +2
Mutually Unbiased Bases (MUBs) are closely connected with quantum physics, and the structure has a rich mathematical background. We provide equivalent criteria for extending a set…
Almost Perfect Mutually Unbiased Bases that are Sparse
Ajeet Kumar, Subhamoy Maitra, Somjit Roy
In dimension , Mutually Unbiased Bases (MUBs) are a collection of orthonormal bases over such that for any two vectors belonging to different bases, th…
Further Constructions of AMUBs for Non-prime power Composite Dimensions
Ajeet Kumar, Subhamoy Maitra
Construction of a large class of Mutually Unbiased Bases (MUBs) for non-prime power composite dimensions () is a long standing open problem, which leads to different…
