Versatile Photonic Entanglement Synthesizer in the Spatial Domain
Abstract Multimode entanglement is an essential resource for quantum information in continuous-variable systems. Light-based quantum technologies will arguably not be built upon table-top bulk setups, but will presumably rather resort to integrated optics. Sequential bulk opticslike proposals based on cascaded …

Effect of sintering germanium epilayers on dislocation dynamics: From theory to experimental observation
Abstract High-quality germanium epilayers on Si with low threading-dislocation density were achieved by sintering of porous Ge/Si films. The process consists in the formation of porous Ge nanostructures by …

Entropy reduces the lifetime of magnetic bits
Retaining stored information in magnetic materials relies on making energy barriers difficult to overcome. In a theoretical study, two researchers at C2N show that the resulting entropy can have the opposite effect. Their results challenge …
