Proves minimal operator systems over positive semidefinite and Lorentz cones lack subhomogeneity, establishing bounds on entangled quantum states with only separable compressions—fundamental insight into quantum entanglement structure.

Investigates two-parameter families of linear maps on matrix algebras via diagonal perturbations of classical Tomiyama maps, deriving explicit conditions for positivity and k-positivity using Choi matrix and block-positivity techniques.

Exploring quantum distances and means.

This paper establishes variational principles for quantum α-z fidelity, applies it to measure distances between quantum orbits, and studies the α-z-weighted right mean: doi.org/10.1142/S021...
