Description:
Author(s): Qi Guo, Juan Bai, Liu-Yong Cheng, Xiao-Qiang Shao, Hong-Fu Wang, and Shou Zhang We propose a simplified parity meter for photonic qubits with cross-Kerr nonlinearities, homodyne measurement, and some optical elements. Our scheme has lower error probability than the protocol proposed in Nemoto and Munro [ Phys. Rev. Lett. 93 , 250502 (2004) ]. Based on the present parity meter, we ... [Phys. Rev.
