Query: On some links between quantum physics and gravitation   It is widely believed that quantum gravity effects are negligible in a
conventional laboratory experiment because quantum gravity should play its role
only at a distance of about Planck's length ($\sim10^{-33}$ cm). Sometimes that
is not the case as shown in this article. We discuss two new ideas about
quantum physics connections with gravity. First, the Hong-Ou-Mandel effect
relation to quantum gravity is examined. Second, it is shown that the very
existence of gravitons is a consequence of quantum statistics. Moreover, since
the Bose-Einstein statistics is a special case of Compound Poisson
Distribution, it predicts the existence of an infinite family of high-spin
massless particles.
