Diagonal unitary and orthogonal symmetries in quantum theory II: Evolution operators
Satvik Singh, Ion Nechita
We study bipartite unitary operators which stay invariant under the local actions of diagonal unitary and orthogonal groups. We investigate structural properties of these operators…

Coherent information of a quantum channel or its complement is generically positive
Satvik Singh, Nilanjana Datta
The task of determining whether a given quantum channel has positive capacity to transmit quantum information is a fundamental open problem in quantum information theory. In genera…

Detecting positive quantum capacities of quantum channels
Satvik Singh, Nilanjana Datta
Determining whether a noisy quantum channel can be used to reliably transmit quantum information at a non-zero rate is a challenging problem in quantum information theory. This is…
