Quantum complementarity is the essential feature distinguishing quantum from classical physics.
When two physical observables are complementary, the precise knowledge of one of them makes the other unpredictable. The most known manifestation of this principle is the property of quantum-mechanical entities to behave either as particles or as waves under different experimental conditions. The link between quantum correlations, quantum nonlocality and Bohr’s complementarity principle was established in a series of “which-way” experiments, in which the underlying idea is the same as in Young’s double-slit experiment. Due to its wave-like nature, a particle can be set up to travel along a quantum superposition of two different paths, resulting in an interference pattern. If however a “which-way” detector is employed to determine the particle’s path, the particle like behavior takes over and an interference pattern is no longer observed. These experiments have brought evidence that the loss of interference is not necessarily a consequence of the back action of a measurement process. Quantum complementarity is rather an inherent property of a system, enforced by quantum correlations. This manifestation of quantum mechanics enables random fusion energy distribution for cavity polaritons. Polaritons in micro-cavities are hybrid quasiparticles consisting of a superposition of cavity photons and two-dimensional collective electronic excitations (excitons) in an embedded quantum well. Owing to their mutual Coulomb interaction, pump polaritons generated by a resonant optical excitation can scatter resonantly into pairs of polaritons (signal and idler). In the low excitation limit, the polariton parametric scattering is a spontaneous process driven by vacuum-field fluctuations whereas, already at moderate excitation intensity, it displays self-stimulation. In either of these two cases where the fusion energy goes is directed by the luck of the draw and the randomness of the vacuum energy within the nano-cavity.
