Quantum Fredkin and Toffoli gates on a versatile programmable silicon photonic chip
Abstract Quantum logic gates are backbones of quantum information processing (QIP), wherein the typical three-qubit Fredkin and Toffoli gates are essential in quantum computation and communication.So far, the quantum Fredkin gate has only been demonstrated with pre-entangled input states in free-space optics, which limits its usage glitter foam vel
