Abstract Graphs have provided an expressive mathematical tool to model quantum-mechanical devices and systems. In particular, it has been recently discovered that graph theory can be used describe design quantum components, devices, setups systems, based on the two-dimensional lattice of parametric nonlinear optical crystals linear circuits, different standard photonic framework. Realizing such graph-theoretical hardware, however, remains extremely challenging experimentally using...
Quantum networks provide the framework for quantum communication, clock synchronization, distributed computing, and sensing. Implementing large-scale practical relies on development of scalable architecture integrated hardware that can coherently interconnect many remote nodes by sharing multidimensional entanglement through complex-medium channels.

Electrochemical corrosion behavior of ternary tin-zinc-yttrium (Sn-9Zn-xY) solder alloys were investigated in aerated 3.5 wt.% NaCl solution using potentiodynamic polarization techniques, and the microstructure evolution was obtained by scanning electron microscope (SEM). Eight different compositions Sn-9Zn-xY (x = 0, 0.02, 0.04, 0.06, 0.08, 0.10, 0.20, 0.30 wt.%) compared melting.

Characterization and categorization of quantum correlations are both fundamentally practically important in information science. Although such as non-separability, steerability, non-locality can be characterized by different theoretical models scenarios with either known (trusted) or unknown (untrusted) knowledge the associated systems, characterization sometimes lacks unambiguous to experimentalist. In this work, we propose physical interpretation nonlocal correlation between two systems....
