Using the adiabatic quantum-flux-parametron (AQFP), as a building block researchers in Japan have developed and demonstrated a prototype 4-bit AQFP microprocessor called MANA (Monolithic Adiabatic iNtegration Architecture). The AQFP is capable of data processing and data storage, it can operate up to a clock frequency of 2.5 GHz making this on par with today’s computing technologies. They expect this to increase to 5-10 GHz as they make improvements in design methodology and experimental setup. According to the researchers even when taking this cooling overhead into account, the AQFP is still about 80 times more energy-efficient when compared to the state-of-the-art semiconductor electronic devices found in high-performance computer chips available today…read more.
