The thesis proposes using a polarization-based displaced Sagnac-type interferometer to achieve partial collapse measurement and its reversal, and presents the first experimental verification of the nonlocality of the partial collapse measurement and its reversal. All of the experiments are carried out in the linear optical system, one of the earliest experimental systems to employ quantum communication and quantum information processing. The thesis argues that quantum measurement can yield quantum entanglement recovery, which is demonstrated by using the frequency freedom to simulate the environment. Based on the weak measurement theory, the author proposes that white light can be used to precisely estimate phase, and effectively demonstrates that the imaginary part of the weak value can be introduced by means of weak measurement evolution. Lastly, a nine-order polarization-based displaced Sagnac-type interferometer employing bulk optics is constructed to perform quantum simulation of the Landau-Zener evolution, and by tuning the system Hamiltonian, the first experiment to research the Kibble-Zurek mechanism in non-equilibrium kinetics processes is carried out in the linear optical system.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Quantum theoryQuantum computersQuantum opticsQuantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Quantum Computinghttps://scigraph.springernature.com/ontologies/product-market-codes/M14070Quantum Opticshttps://scigraph.springernature.com/ontologies/product-market-codes/P24050Quantum theory.Quantum computers.Quantum optics.Quantum Physics.Quantum Computing.Quantum Optics.530.12Xu Xiaoyeauthttp://id.loc.gov/vocabulary/relators/aut1062622MiAaPQMiAaPQMiAaPQBOOK9910254639903321Applied Research of Quantum Information Based on Linear Optics2527096UNINA
