Transmission of a quantum state in a periodically poled nonlinear crystal

Abstract

Theoretical calculations on transmission of quantum states such as Schrödinger cat (SC) states are considered in a periodically poled nonlinear crystal (PPNC). Combinations of various initial states (SC, coherent (C),and vacuum (V)) of light waves at frequencies $ω_{e}$ and $3ω_{e}$ at the input of a PPNC are studied. It is shown that the transmission and interference between superposition of macroscopically distinguishable states can be achieved by using a PPNC. Visualization and analyzes of transmission and interference processes are demonstrated with the help of reduced Wigner quasi-probability distribution functions of considered light waves.

Frequency up-conversion of an even coherent state

Aleksandr V. Belinsky, Ranjit Singh

The problem of transferring the state of even coherent states from a low frequency to a high frequency is theoretically considered using a periodically-poled nonlinear crystal. With the help of the Wigner quasi-probability distribution function, a parallel implementation of two nonlinear processes is studied: parametric and sum frequency generation.

Statistical Characteristics of Quantum Polarization States Formed in Periodically Poled Nonlinear Crystals: Mathematical Modeling

Aleksandr V. Belinsky, Ranjit Singh

Abstract A degenerate parametric process and the complete upward generation of ordinary and extraordinary optical waves inside a periodically poled nonlinear crystal (PPNC) with quadratic nonlinearity are considered. A quantum theory is developed for describing statistical characteristics of the polarized states of light in a PPNC. It is found that the degree of polarization can be controlled by creating an imbalance in the intensity of modes at frequencies of ordinary and extraordinary optical waves (i.e., reducing the average number of photons in one and increasing it in the other).

Interaction of light waves in active nonlinear and periodically poled nonlinear crystals

Лаптев Георгий Дмитриевич, A. A. Novikov, A. S. Chirkin

The results of classical and quantum studies of the laser-radiation self-frequency conversion processes in periodically poled active nonlinear crystals are overviewed. The theoretical and experimental results of studying quasi-phase-matched self-frequency doubling and summation of the laser and pump frequencies in an active nonlinear periodically poled Nd:Mg:LiNbO 3 crystal are presented. The possibility of producing frequency-and polarization-entangled states and the sub-Poisson field statistics through a consecutive nonlinear optical frequency conversion in periodically poled nonlinear crystals is considered.
