A group of researchers from the Institute of Advanced Sciences at Yokohama National University, in Japan, have developed the MANA (Monolithic Adiabatic iNtegration Architecture) microprocessor. Highlights of the development are that: the MANA chip is a superconducting microprocessor; and even accounting for the energy required to cool it down to 4.2 Kelvin, it is said to be 80x more efficient than a state-of-the-art 7-nm FinFET semiconductor rival. Interestingly, MANA is composed of superconducting niobium and built from adiabatic quantum-flux-parametrons (AQFPs). Each of these AQFP is composed of a few fast-acting Josephson junction switches – and in the prototype MANA processor there are more than 20,000 Josephson junctions in total.
