WebFor polynomial functions, these criteria are related to Hilbert's 17th problem, and have physical meaning of generalized squeezing conditions; alternatively, they may be interpreted as nonclassicality witnesses. We show that every generic nonclassical state can be detected by a polynomial that is a sum-of-squares of other polynomials.

Math.U.Phys.(3),1,(1901) 44-63,213-237 (one can also ﬁnd it in Hilbert’s Gesammelte Werke). The fourteenth problem may be formulated as follows: The Four-teenth Problems. Hilbert's seventeenth problem is one of the 23 Hilbert problems set out in a celebrated list compiled in 1900 by David Hilbert. It concerns the expression of positive definite rational functions as sums of quotients of squares. The original question may be reformulated as: Given a multivariate polynomial … See more The formulation of the question takes into account that there are non-negative polynomials, for example $${\displaystyle f(x,y,z)=z^{6}+x^{4}y^{2}+x^{2}y^{4}-3x^{2}y^{2}z^{2},}$$ See more It is an open question what is the smallest number $${\displaystyle v(n,d),}$$ such that any n-variate, non-negative polynomial of degree d can be written as sum of at most $${\displaystyle v(n,d)}$$ square rational … See more The particular case of n = 2 was already solved by Hilbert in 1893.
