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. https://www.bekindtopets.com/bargain-Speedrite-S500-Solar-Charger-must-buy/
