Kadison duality for partially convex sets
Tea Å trekelj
This paper extends the Kadison duality between compact convex sets and function systems to the setting of partial convexity. A partially convex set is a set that is convex in a des…
Quantum Max Cut for complete tripartite graphs
Tea Å trekelj
The Quantum Max--Cut (-QMC) problem is a special instance of a -local Hamiltonian problem, representing the quantum analog of the classical Max--Cut problem. The -QM…
Quantum Max d-Cut via qudit swap operators
Igor Klep, Tea Å trekelj, Jurij VolÄiÄ
Quantum Max Cut (QMC) problem for systems of qubits is an example of a 2-local Hamiltonian problem, and a prominent paradigm in computational complexity theory. This paper investig…
Construction of exceptional copositive matrices
Tea Štrekelj, Aljaž Zalar
An symmetric matrix is copositive if the quadratic form is nonnegative on the nonnegative orthant . The cone of copositive matrices…
