QUIC talk: Measurement sharpness cuts nonlocality and contextuality in every phy
Abstract: Gathering data through measurements is at the basis of every experimental science. Ideally, measurements should be repeatable and, when extracting only coarse-grained data, they should allo...

Quantum Journal Club: Pattern Formation with Trapped Ions
Abstract: Ion traps are a versatile tool to study nonequilibrium statistical physics, due to the tunability of dissipation and nonlinearity.We propose an experiment with a chain of ions, where dissip...

Quantum Nonlinear Optics Using Quantum Memory
Abstract: Large nonlinearity at the single-photon level can pave the way for the implementation of universal quantum gates. However, realizing large and noiseless nonlinearity at such low light level...

Quantum Journal Club: Control of the conformations of ion Coulomb crystals in a
Abstract: 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 i...
