Complementary Resource Relation of Concurrence and Roughness for atwo Qubits State

Quantum Physics 2022-12-14 v1

Abstract

Quantum resources lie at the core of quantum computation as they are responsible for the computational advantage in many tasks. The complementary relations are a pathway to understanding how the physical quantities are related. Here it was shown that there is a complementary relationship that evolves quantumness of a two qubits state and the degree of entanglement, respectively measured by Roughness and Concurrence. It was shown that there is a R2\mathbb{R}^2 surface that characterizes these quantities and can be understood as a projection of the Bloch Sphere. The distribution of states on the surface shows a concentration in the region of lower roughness and Concurrence, i.e., in the subset of states of greater entropy.
