A full optical method to realize quantum computation is proposed. Because quantum entanglement is considered as a key property to realize the quantum computation, we further discuss "mode-entangled states" based on the optical transverse modes of the optical field propagating in multimode waveguides, which are classical simulation of the quantum entangled states. The simulation is discussed in detail, including the violation of the Bell inequality and the correlation properties of optical pulses' group delays. These properties can be regarded as the proofs of the existence of the mode-entangled states. The research on this simulation may be important, for it not only provides useful insights into fundamental features of quantum entanglement, but also yields interesting insights into quantum computation and quantum communication. The paper consists of 4 chapters.Chapter 1: This chapter is an introduction to quantum computation, include quantum bit, quantum gate, quantum Fourier transform and the famous Shor's algorithm.Chapter 2: A full optical method to realize quantum computation is proposed. TEo mode and TE1 mode in waveguide are used as qubits to represent logical 0 and 1. Mach-Zehnder interferometer, directional couplers and Kerr-like mediums such as semiconductor optical amplifiers are used to construct CNOT gate.Chapter 3: "Mode-entangled states" based on the optical transverse modes of the optical field propagating in multimode waveguides are discussed, which are classical simulation of the quantum entangled states. The simulation is discussed in detail, including the violation of the Bell inequality and the correlation properties of optical pulses' group delays.Chapter 4: The summary reviews the possible significance of the work.
