Simultaneous symplectic spectral decomposition of positive semidefinite matrices
Rudra R. Kamat, Hemant K. Mishra
We establish necessary and sufficient conditions on simultaneous symplectic spectral decomposition of a family of real positive semidefinite matrices with symplectic…
Barycentric bounds on the error exponents of quantum hypothesis exclusion
Kaiyuan Ji, Hemant K. Mishra, Milán Mosonyi +1
Quantum state exclusion is an operational task with application to ontological interpretations of quantum states. In such a task, one is given a system whose state is randomly sele…
Multivariate Fidelities
Theshani Nuradha, Hemant K. Mishra, Felix Leditzky +1
The main contribution of our paper is to introduce a number of multivariate quantum fidelities and show that they satisfy several desirable properties that are natural extensions o…
Orthosymplectic diagonalization in Williamson's theorem
Hemant K. Mishra
In this paper, we provide an algebraic condition on any real symmetric positive definite matrix which is necessary and sufficient for the matrix to be diagonalized b…
