System Bits: Oct. 3


Polariton graphs In a development that a team of researchers from the UK and Russia say could eventually surpass the capabilities of even the most powerful supercomputers, a type of ‘magic dust’ — which combines light and matter — can be used to solve complex problems. Hailing from the University of Cambridge, University of Southampton and Cardiff University in the UK and the Skolk... » read more

Power/Performance Bits: Sept. 22


Photonic memories A team of researchers from Oxford University, the University of Münster, the Karlsruhe Institute of Technology, and the University of Exeter produced the first all-photonic nonvolatile memory chip. The new device uses the phase-change material Ge2Sb2Te5 (GST), used in rewritable CDs and DVDs, to store data. This material can be made to assume an amorphous state, like glass... » read more
