Low-Power Quantum Computers
Posted in Electronics & Computers, Power Management, Computers, Energy Efficiency, News on Monday, 12 December 2011
By 2017, quantum physics will help reduce the energy consumption of computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. The next step will likely come from tunnel-FET, a technology that takes advantage of a phenomenon referred to as quantum tunneling. At the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, research is well underway.
