Quantum Max d-Cut via qudit swap operators
Igor Klep, Tea Štrekelj, Jurij Volčič
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…
Duality, extreme points and hulls for noncommutative partial convexity
Igor Klep, Scott McCullough, Tea Štrekelj
This article studies generalizations of (matrix) convexity, including partial convexity and biconvexity, under the umbrella of -convexity. Here is a tuple of free symmetric…
A random copositive matrix is completely positive with positive probability
Igor Klep, Tea Štrekelj, Aljaž Zalar
An symmetric matrix is copositive if the quadratic form is nonnegative on the nonnegative orthant. The cone of copositive matrices strictly contains the con…
Convexity of a certain operator trace functional
Eric Evert, Scott McCullough, Tea Štrekelj +1
In this article the operator trace function is introduced and its convexity and concavity properties are investigated.…
Facial structure of matrix convex sets
Igor Klep, Tea Štrekelj
This article investigates the notions of exposed points and (exposed) faces in the matrix convex setting. Matrix exposed points in finite dimensions were first defined by Kriel in…
