The operator theory required for quantum information processing and transmission is already well developed for what are known as self-adjoint operators, which are used to describe the different ...

Quantum mechanics is underpinned by a variety of models that elucidate the interplay between particles and potentials. Among these, point interactions – often mathematically represented by Dirac delta ...

Operator algebras and functional analysis form a foundational framework in modern mathematics, interlinking abstract algebraic structures with analytic techniques to study infinite‐dimensional spaces.
