In 2009, researchers discovered that [[memristor]]s can implement a Boolean state storage and provides a complete logic family with very small amounts of space and power, using familiar CMOS semiconductor processes.<ref>{{cite conference |last1=Lehtonen |first1=Eero |last2=Laiho |first2=Mika |work=2009 IEEE/ACM International Symposium on Nanoscale Architectures |title=Stateful implication logic with memristors |date=2009 |pages=33–36 |doi=10.1109/NANOARCH.2009.5226356|isbn=978-1-4244-4957-6 }}</ref>

The discovery of [[superconductivity]] has enabled the development of [[rapid single flux quantum]] (RSFQ) circuit technology, which uses [[Josephson junction]]s instead of transistors. Most recently, attempts are being made to construct purely [[optical computing]] systems capable of processing digital information using [[Nonlinear optics|nonlinear optical elements]].
