Uncertainty relations for general unitary operators
Shrobona Bagchi, Arun Kumar Pati
We derive several uncertainty relations for two arbitrary unitary operators acting on physical states of a Hilbert space. We show that our bounds are tighter in various cases than…

Generalized Geometric Measure of Entanglement for Multiparty Mixed States
Tamoghna Das, Sudipto Singha Roy, Shrobona Bagchi +3
Computing entanglement of an arbitrary bipartite or multipartite mixed state is in general not an easy task as it usually involves complex optimization. Here we show that exploitin…

Monogamy, polygamy, and other properties of entanglement of purification
Shrobona Bagchi, Arun Kumar Pati
For bipartite pure and mixed quantum states, in addition to the quantum mutual information, there is another measure of total correlation, namely, the entanglement of purification.…
