Abstract
Optics has been successfully used for data processing. The basic building blocks of quantum computers are the quantum gates. Here, a quantum CNOT gate is proposed. To implement the gate advantages of polarization-based encoding technique and optical Kerr material-based switching are utilized. CS2 can show this type of switching feature. An Nd-YAG laser source of 1.064 μm wavelength is used to implement the scheme. Intensity of the laser pulse should be of the order of 1018 W/m2 to excite the 2nd order nonlinearity of the isotropic nonlinear material.
