Abstract

ABSTRACT We report on the theoretical design and simulation of a photonic quantum circuit that operates as a single-photon, two-qubit swap gate. In this approach, the circuit is implemented in Titanium indiffused LiNbO3 channel waveguides, and polarization and spatial encoding are utilized to realize the qubits. A set of basic components comprising a dual periodically poled waveguide for two simultaneous Type-0 and Type-I non-linear interactions, as well as the passive routing and active electro-optically controllable devices, are the main building blocks in this circuit. Simulations are carried out by making use of the numerical beam propagation method incorporated within RSoft program package.

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
