[[Niels Bohr]] interpreted quantum experiments like the double-slit experiment using the concept of complementarity.<ref name="Faye-Stanford">{{Cite book|last=Faye|first=Jan|title=[[Stanford Encyclopedia of Philosophy]]|publisher=Metaphysics Research Lab, Stanford University|year=2019|editor-last=Zalta|editor-first=Edward N.|chapter=Copenhagen Interpretation of Quantum Mechanics|author-link=Jan Faye|chapter-url=https://plato.stanford.edu/entries/qm-copenhagen/}}</ref> In Bohr's view quantum systems are not classical, but measurements can only give classical results. Certain pairs of classical properties will never be observed in a quantum system simultaneously: the interference pattern of waves in the double slit experiment will disappear if particles are detected at the slits. Modern quantitative versions of the concept allow for a continuous tradeoff between the visibility of the interference fringes and the probability of particle detection at a slit.<ref>{{Cite journal |last1=Wootters |first1=William K. |last2=Zurek |first2=Wojciech H. |date=1979-01-15 |title=Complementarity in the double-slit experiment: Quantum nonseparability and a quantitative statement of Bohr's principle |url=https://link.aps.org/doi/10.1103/PhysRevD.19.473 |journal=Physical Review D |language=en |volume=19 |issue=2 |pages=473–484 |doi=10.1103/PhysRevD.19.473 |bibcode=1979PhRvD..19..473W |issn=0556-2821}}</ref><ref>{{Cite journal |last=Bartell |first=L.
