Abstract: Systems and methods of performing logical operations with photonic quantum logic gates. The logic gates utilize photon states, usually orthogonal linearly polarized states, to selectively enact self-interference operations whose outputs can be altered by inducing phase shifts in one or more portions of the section of the logic gate where the photon states undergo self-interference. The polarization direction switchings are differentially enacted and/or not enacted, in groupings of switches, to perform various logic operations. Additionally, networked logic gates with interrelated self-interference section phase shifts and output states are described that provide additional capabilities.

Abstract: Systems and methods are described for processing quantum entity states by utilizing interference phenomena, and more specifically self-interference outcomes. The quantum entity states are embodiable in fermions and/or bosons, expressly including photons. Certain embodiments can utilize input quantum entity states that encompass one or more separable quantum entities and can be arranged to produce predictable outcome differences that are alterable in accordance with differences and/or similarities between separate input quantum entities. Additional outcome alterations are effectible via static and/or dynamic quantum entity state influencing constituents. Even further outcome alterations are effectible by associative quantum state influencing constituents that are additionally utilizable for interrelating separable embodiments.

Abstract: A system including methods and apparatuses for responding to an entity's superposition of states. The system is also able to respond to a first entity's state of entanglement, as well as respond to either the superposition of states or entanglement of any other entity that is entangled with the first entity. The system is capable of effecting its responses to superpositions of states or entanglements in modes that can preserve or demolish the superposition of states or entanglements of the entities it interacts with. The system is able to selectively switch between these modes of responses, and can also effect its responses in a delayed-choice manner. The system also encompasses applications of the methods and apparatuses for purposes including quantum communication, quantum computation, and quantum cryptography.
