SIMPLE EXPERIMENTAL SETUPS FOR OBSERVING WAVE-PARTICLE AND ENTANGLEMENT-SEPARABILITY SUPERPOSITIONS

NGUYEN BA AN

It has been long believed that wave and particle cannot be superposed. Recently, however, modern quantum techniques have allowed one to prepare photon wave-particle superpositions experimentally. In this work, we suggest simple setups, which resort to neither any extra quantum resources nor controlled-Hadamard gates, to observe such superpositions as well as entanglement-separability superpositions with tunable entanglement degree. The suggested setups can also serve as an interaction-free method to detect partially absorbing objects.
