Complexidade de estados quânticos: o papel do entrelaçamento.

Abstract

The role of complexity measures has become increasingly clear on the extent of understanding we have of complex systems. However, despite the large number of measures proposed to capture these characteristics in classical systems, to quantum systems there are only extensions of the Kolmogorov's algorithmic complexity. Thus, this work proposes the extension of three measures of complexity by using the tools of quantum information theory to make them able to understand the quanti cation of the complexity of quantum states. Results show that some phenomena observed in classical complex systems are present in bipartite and tripartite states of qubits and are closely linked with the presence of entanglement in them. Both proof of known concepts as signs of new phenomena were observed, with possible technological applications.
