Priority Choice Experimental Two-Qubit Tomography: Measuring One by One All Elements of Density Matrices
In standard optical tomographic methods, the off-diagonal elements of a density matrix ρ are measured indirectly. Thus, the reconstruction of ρ, even if it is based on linear inversion, typically magnifies small errors in the experimental data. Recently, an optimal tomography solution measuring all the elements of ρ one-by-one without error magnification has been theoretically proposed. We impl...
متن کاملExperimental Demonstration of Self-Guided Quantum Tomography.
Traditional methods of quantum state characterization are impractical for systems of more than a few qubits due to exponentially expensive postprocessing and data storage and lack robustness against errors and noise. Here, we experimentally demonstrate self-guided quantum tomography performed on polarization photonic qubits. The quantum state is iteratively learned by optimizing a projection me...
متن کاملIncreasing the Capacity and PSNR in Blind Watermarking Resist Against Cropping Attacks
Watermarking has increased dramatically in recent years in the Internet and digital media. Watermarking is one of the powerful tools to protect copyright. Local image features have been widely used in watermarking techniques based on feature points. In various papers, the invariance feature has been used to obtain the robustness against attacks. The purpose of this research was based on local f...
متن کاملRobust Agent Based Distribution System Restoration with Uncertainty in Loads in Smart Grids
This paper presents a comprehensive robust distributed intelligent control for optimum self-healing activities in smart distribution systems considering the uncertainty in loads. The presented agent based framework obviates the requirements for a central control method and improves the reliability of the self-healing mechanism. Agents possess three characteristics including local views, decentr...
متن کاملOptimal conditions for Bell-inequality violation in the presence of decoherence and errors
We obtain the set of all detector configurations providing the maximal violation of the Bell inequality in the Clauser–Horne–Shimony–Holt form for a general (pure or mixed) state of two qubits. Next, we analyze optimal conditions for the Bell-inequality violations in the presence of local decoherence, which includes energy relaxation at the zero temperature and arbitrary pure dephasing. We reve...
