Covariance matrix entanglement criterion for an arbitrary set of operators
Vinay Tripathi, Chandrashekar Radhakrishnan, Tim Byrnes
We generalize entanglement detection with covariance matrices for an arbitrary set of observables. A generalized uncertainty relation is constructed using the covariance and commut…

Basis-independent quantum coherence and its distribution
Chandrashekar Radhakrishnan, Zhe Ding, Fazhan Shi +2
We analyze a basis-independent definition of quantum coherence. The maximally mixed state is used as the reference state, which allows for a way of defining coherence that is invar…
