Moore's law and the energy requirement of computing versus performance

It has recently been recoginsed that speed, noise and energy dissipation are strongly interrelated entities. Following Moore's law of miniaturisation, at sizes below 40nm, physics will impose fundamental and practical limits of performance by shrinking noise margin, increasing and quickening noise, and increasing power dissipation. It is important to locate the fundamental aspects of the problem, explore relevant practical problems and possible solutions, and investigate this situation, not only in microelectronics (CMOS etc.) but also in single-electron-transistor-based nanoelectronics and also in quantum informatics applications. The energy requirement of running classical and quantum logic gates is compared.
