Square Root Of "Not": A Major Difference Between Fuzzy And Quantum Logics, Vladik Kreinovich, Ladislav J. Kohout, Eunjin Kim

Departmental Technical Reports (CS)

Many authors have mentioned the similarity between quantum logic and fuzzy logic. In this paper, we show that, in spite of this similarity, these logics are not identical. Specifically, we emphasize that while quantum logic has a special ``square root of not'' operation which is very useful in quantum computing, fuzzy logic lacks such an operation.
