Quantum Journal Club: Experimental Violation of Multipartite Bell Inequalities w
内容： We report on the experimental violation of multipartite Bell inequalities by entangled states of trapped ions. First, we consider resource states for measurement-based quantum computation of be...

Quantum Journal Club: Control of the conformations of ion Coulomb crystals in a
内容： Laser-cooled atomic ions form ordered structures in radiofrequency ion traps and in Penning traps. Here we demonstrate in a Penning trap the creation and manipulation of a wide variety of ion C...

Quantum Journal Club: Observation of quantum state collapse and revival due to t
内容： To create and manipulate non-classical states of light for quantum information protocols, a strong, nonlinear interaction at the singlephoton level is required. One approach to the generation o...

Quantum Journal Club: Quantum Discord Cannot Be Shared
内容： Bohr proposed that the outcome of a measurement becomes objective and real, and, hence, classical, when its results can be communicated by classical means. In this work we revisit Bohr’s postu...
