Quantum physics phenomena, entanglement and coherence, are crucial for quantum information protocols, but understanding these in systems with more than two parts is …
Bell nonclassicality of a single-photon superposition in two modes, often referred to as “nonlocality of a single photon,” is one of the most striking nonclassical phenomena …
We investigate the single-particle multi-mode" entanglement" and raise the questions: Is a single particle always entangled? Is entanglement a physical reality which is invariant under …
