Classification of nonlocal two-qubit gates using Schmidt number
S Balakrishnan, Leona J Felicia, R Sankaranarayanan
It is known from Schmidt decomposition that Schmidt number of nonlocal two-qubit quantum gates is 2 or 4. We identify conditions on geometrical points of a gate to have Schmidt num…

Characterizing the geometrical edges of nonlocal two-qubit gates
S. Balakrishnan, R. Sankaranarayanan
Nonlocal two-qubit gates are geometrically represented by tetrahedron known as Weyl chamber within which perfect entanglers form a polyhedron. We identify that all edges of the Wey…
