A minimal completion theorem and almost everywhere equivalence for Completely Positive maps

B. V. Rajarama Bhat, Arghya Chongdar

A problem of completing a linear map on C*-algebras to a completely positive map is analyzed. It is shown that whenever such a completion is feasible there exists a unique minimal…

Error Basis and Quantum Channel

B. V. Rajarama Bhat, Purbayan Chakraborty, Uwe Franz

The Weyl operators give a convenient basis of $M_{n} (C)$ which is also orthonormal with respect to the Hilbert-Schmidt inner product. The properties of such a basis can be g…

Operator moment dilations as block operators

B. V. Rajarama Bhat, Anindya Ghatak, Santhosh Kumar Pamula

Let $H$ be a complex Hilbert space and let ${A_{n}}_{n \geq 1}$ be a sequence of bounded linear operators on $H$ . Then a bounded operator $B$ on a Hilb…

Schoenberg Correspondence for $k$ -(Super)Positive Maps on Matrix Algebras

B. V. Rajarama Bhat, Purbayan Chakraborty, Uwe Franz

We prove a Schoenberg-type correspondence for non-unital semigroups which generalizes an analogous result for unital semigroup proved by Michael Schürmann. It characterizes the gen…
