Error Basis and Quantum Channel
B. V. Rajarama Bhat, Purbayan Chakraborty, Uwe Franz
The Weyl operators give a convenient basis of which is also orthonormal with respect to the Hilbert-Schmidt inner product. The properties of such a basis can be g…

On the equivalence of separability and extendability of quantum states
B. V. Rajarama Bhat, K. R. Parthasarathy, Ritabrata Sengupta
Motivated by the notions of -extendability and complete extendability of the state of a finite level quantum system as described by Doherty et al (Phys. Rev. A, 69:022308), we i…

A completely entangled subspace of maximal dimension
B. V. Rajarama Bhat
A completely entangled subspace of a tensor product of Hilbert spaces is a subspace with no non-trivial product vector. K. R. Parthasarathy determined the maximum dimension possibl…
