On regions of mixed unitarity for semigroups of unital quantum channels
B V Rajarama Bhat, Repana Devendra
It is established that both discrete and continuous semigroups of unital quantum channels are eventually mixed unitary. This result is novel even for the subclass of Schur maps and…
Understanding Quantum Instruments Through the Analysis of -Convexity and Their Marginals
B. V. Rajarama Bhat, Arghya Chongdar, Sruthymurali
Quantum instruments are mathematical devices introduced to describe the conditional state change during a quantum process. They are completely positive map valued measures on measu…
Peripheral Poisson Boundary: Extensions and Examples
B V Rajarama Bhat, Astrid Swizell Dias
The main purpose of this article is to explore the possibility of extending the notion of peripheral Poisson boundary of unital completely positive (UCP) maps to contractive comple…
Unitary orthonormal bases of finite dimensional inclusions
Keshab Chandra Bakshi, B V Rajarama Bhat
We study unitary orthonormal bases in the sense of Pimsner and Popa for inclusions where are finite dimensional…
