Abstract
In this work, we experimentally demonstrate the quantum interference of force effect using pairs of entangled photons. Although photons are massless particles, they have linear momentum, and our experiments show that the quantum superposition of a positive momentum transfer with a null momentum transfer may result in a negative momentum transfer to an ensemble of quantum particles (photons), a behavior with no classical analog. The momentum transfer to each photon is defined by the result of a polarization measurement performed in a second photon, initially entangled with it.
