Nonlinear properties of quantum states, such as entropy or entanglement, quantify important physical resources and are frequently used in quantum-information science. They are usually calculated from a full description of a quantum state, even though they depend only on a small number of parameters that specify the state. Here we extract a nonlocal and a(More)

Purpose/Aim: In the past few decades some researchers have questioned whether bursectomy for gastric cancer is essential from an oncological point of view and no consistent recommendations have been proposed. The aim of this systematic review with meta-analysis is to investigate the oncologic effectiveness and safety of bursectomy for the treatment of(More)
We implemented the experiment proposed by Cabello in the preceding Letter to test the bounds of quantum correlation. As expected from the theory we found that, for certain choices of local observables, Tsirelson's bound of the Clauser-Horne-Shimony-Holt inequality (2 x square root of 2) is not reached by any quantum states.
