- Very-large-scale integrated quantum graph photonics - Graphs have provided an expressive mathematical tool to model quantum-mechanical devices and systems. In particular, it has been recently discovered that graph theory can be used to describe and design quantum components, devices, setups and systems, based on the two-dimensional lattice of parametric nonlinear optical crystals and linear optical circuits, different to the standard quantum photonic framework. Realizing such graph-theoretical quantum photonic hardware, however, remains extremely challenging experimentally using conventional technologies. Here we demonstrate a graph-theoretical programmable quantum photonic device in very-large-scale integrated nanophotonic circuits. The device monolithically integrates about 2,500 components, constructing a synthetic lattice of nonlinear photon-pair waveguide sources Read More
- The State of IC and ASIC Functional Verification - Way back in 2002 there was a study from Collett International Research on functional verification, and since 2010 the Wilson Research Group has continued that same kind of study with a new report every two years. What attracts me to this report is that it doesn’t just look at the installed base of one EDA vendor, instead it looks across the world asking questions of design and verification engineers, so that the rest of us in the semiconductor industry can understand what the trends are for functional verification. Our global semiconductor market had a total value of $547 billion in Read More
