Applied Research of Quantum Information Based on Linear by Xiaoye Xu

By Xiaoye Xu

This thesis stories on amazing paintings in major subfields of quantum info technological know-how: one consists of the quantum dimension challenge, and the opposite matters quantum simulation. The thesis proposes utilizing a polarization-based displaced Sagnac-type interferometer to accomplish partial cave in dimension and its reversal, and provides the 1st experimental verification of the nonlocality of the partial cave in size and its reversal. all the experiments are performed within the linear optical method, one of many earliest experimental structures to hire quantum conversation and quantum info processing. The thesis argues that quantum size can yield quantum entanglement restoration, that's tested through the use of the frequency freedom to simulate the surroundings. in response to the susceptible dimension concept, the writer proposes that white gentle can be utilized to exactly estimate section, and successfully demonstrates that the imaginary a part of the vulnerable worth will be brought by way of vulnerable size evolution. finally, a nine-order polarization-based displaced Sagnac-type interferometer utilizing bulk optics is built to accomplish quantum simulation of the Landau-Zener evolution, and via tuning the procedure Hamiltonian, the 1st scan to investigate the Kibble-Zurek mechanism in non-equilibrium kinetics tactics is performed within the linear optical system.

The general practice is to eliminate the possibility of this part of photon distribution through filters, this 40 1 Basic Concepts of Linear Optical System will inevitably cause brightness reduction. Therefore, it is necessary to discuss the change of degree of entanglement with experimental parameters. The following will discuss the impact of spatial distribution asymmetry of parametric light produced by continuous pump on the degree of entanglement in type-I phase matching. When the pump is focused continuous wave, it can be known from the above section that the distribution of divergence angle of parametric light will increase with pump focusing extent, thus resulting in asymmetric broadening.

1 gives a comparison of the main technical parameters of single photons emitted from different systems (Brahim and Michel 2005; Eisaman et al. 2011; Grangier et al. 2004). 2 Entangled Photons Entangled photons produced in linear optics are used as base on SPDC (Pan et al. 2012), which is a kind of second-order nonlinear optical process. Due to the lower efficiency of such process, the typical value of the second-order nonlinear coefficient for a nonlinear crystal at present is around 10−10 (Sutherland 2003).

For type-II phase matching, similar results can be obtained, given in the following equations and Fig.
