Monotones in general resource theories

T Gonda, RW Spekkens - Compositionality, 2023 - compositionality.episciences.org
In physics there is a long tradition of taking a pragmatic perspective on physical phenomena,
and more specifically of focussing on how certain physical states or processes can constitute …

All multipartite entanglements are quantum coherences in locally distinguishable bases

A Ghoshal, S Choudhary, U Sen - arxiv preprint arxiv:2304.05249, 2023 - arxiv.org
We find that the m-separability and k-partite entanglement of a multipartite quantum system
is correlated with quantum coherence of the same with respect to complete orthonormal …

Correlation between resource-generating powers of quantum gates

A Bhattacharyya, A Ghoshal, U Sen - Physical Review A, 2023 - APS
We analyze the optimal basis for generating the maximum relative entropy of quantum
coherence by an arbitrary gate on a two-qubit system. The optimal basis is not unique and …
