Quantum state swapping in optical quantum communication using Mach-Zehnder interferometer
Quantum state swapping is required for long-distance quantum communication. Quantum state swapping protocols are based on the quantum controlled-NOT (CNOT) or similar quantum logic operations, which are very difficult to implement experimentally. Here we present a feasible scheme for the implementation of Quantum state swapping based on planar lightwave circuit (PLC) implementation of quantum CNOT gate. This quantum gate is realized by using Mach-Zehnder interferometer. By using planar lightwave circuit in implementation, the width of waveguides and the length of CNOT gate were obtained 12 micron and 2.8 cm respectively.
