Products of Idempotents in Banach Algebras of Operators

Surender K. Jain, André Leroy, Ajit Iqbal Singh

Let be a Banach space and be the Banach algebra of bounded (i.e. continuous) linear transformations (to be called operators) on to itself. Let $\mathcal…

Useful variants and perturbations of completely entangled subspaces and spans of unextendible product bases

Ritabrata Sengupta, Ajit Iqbal Singh

Finite dimensional entanglement for pure states has been used extensively in quantum information theory. Depending on the tensor product structure, even set of separable states can…

Polynomial representation for multipartite entanglement of resonating valence bond ladders

Ajit Iqbal Singh, Aditi Sen De, Ujjwal Sen

A resonating valence bond (RVB) state of a lattice of quantum systems is a potential resource for quantum computing and communicating devices. It is a superposition of singlet, i.e…
