===Wavelength-based computing===

Wavelength-based computing<ref>{{cite conference|author=Sama Goliaei, Saeed Jalili|title= An Optical Wavelength-Based Solution to the 3-SAT Problem|conference=Optical SuperComputing Workshop|date=2009|doi=10.1007/978-3-642-10442-8_10| pages=77–85|bibcode=2009LNCS.5882...77G}}</ref> can be used to solve the [[Boolean satisfiability problem#3-satisfiability|3-SAT]] problem with ''n'' variables, ''m'' clauses and with no more than three variables per clause. Each wavelength, contained in a light ray, is considered as possible value-assignments to ''n'' variables. The optical device contains prisms and mirrors are used to discriminate proper wavelengths which satisfy the formula.<ref>{{Cite journal|last1=Bartlett|first1=Ben|last2=Dutt|first2=Avik|last3=Fan|first3=Shanhui|date=2021-12-20|title=Deterministic photonic quantum computation in a synthetic time dimension|url=https://www.osapublishing.org/optica/abstract.cfm?uri=optica-8-12-1515|journal=Optica|language=EN|volume=8|issue=12|pages=1515–1523|doi=10.1364/OPTICA.424258|arxiv=2101.07786|bibcode=2021Optic...8.1515B|s2cid=231639424 |issn=2334-2536}}</ref>
