Description
A crucial goal of quantum technologies is to utilise deviations in properties of quantum system from their classical counterparts as a resource that allows to significantly improve the effectiveness of classical devices. Among such prominent properties of quantum systems are entanglement of states and attainability of negative values of quasiprobability distributions.
In the report, bearing in mind this goal, we present description of resourceful states of finite-dimensional quantum system as complements to the convex sets of separable states and states whose Wigner functions are nonnegative. Several computational aspects of the resource quantification will be exemplified for system of qubits.
