Abstract

Entanglement purification is essential to distill highly entangled states from less entangled ones. Existing general purification 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 entanglement purification based on planar lightwave circuit (PLC) implementation of quantum CNOT gate. This quantum gate is realized by using interferometric electro-optic modulator. 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
