The role of topology in QIS with physical connection to the noncommutativity,discretization,supersymmetry, entanglement, nonseparability and CP violation in physics is discussed.

In the context of the Feynman’s derivation of electrodynamics, we show that noncommutativity allows other particle dynamics than the standard formalism of electrodynamics.

Recently there has been a revival of interest in noncommutative gauge theories. They are interesting examples of nonlocal field theories which in the certain limit (of large noncommutativity) become essentially equivalent to the large N ordinary gauge theories ; certain supersymmetric versions of noncommutative gauge theories arise as α′ → 0 limit of theories on Dp-branes in the presence of bac...

The idea that the geometric structure of physical spacetime could be noncommutative exists in different versions. In some of versions, the noncommutativity of geometry is viewed as a direct effect of quantum mechanics, which disappears in the limit in which we consider processes involving actions much larger than the Planck constant [1]. In the noncommutative geometry approach of Connes et. al....
