As has been predicted for some time, there is a physics train wreck coming at the semiconductor industry - a size and speed where atoms have reached their limits. Quantum computing has remained a dream for 20 years with little progress, which means chips will have to start getting bigger again, to get better performance - or we settle for The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with phase-change materials, which are capable of reversibly switching between two structural phases with different electrical states – one crystalline and conducting and the other glassy and insulating – in billionths of a second. read more
