摘要：
The recent trend of compound semiconductor application and technology is addressed.
Driven by the subjects of 5G/6G, AI, HPC, advanced sensing, machine learning and quantum computing, the intelligent nanophotonics technology developments on laser device and Silicon photonics solutions are introduced.
In addition, a new production technique of NIL (Nanoimprint Lithography) applied to CS industry is commercially updated for a wider range of applications.

Abstract:
The method to solve a strongly interacting quantum many-particle model, the Heisenberg quantum spin chain, devised by Hans Albrecht Bethe in 1931, has since been developed into a versatile set of methodologies to calculate non-perturbatively the physical properties of models of quantum matter. In the nine decades since Bethe’s work, the Bethe ansatz has grown into an important field of mathematical and theoretical physics as both, the method itself and the range of solved models, have been vastly extended. Moreover, it was discovered that the models exhibit an infinite number of conserved quantities: the exactly solved models are quantum integrable. The quantum physical models amenable to an exact solution by Bethe ansatz range from condensed matter and quantum optical physics to quantum field and string
theory and have even fertilised pure mathematics.
We shall concentrate our discussion on condensed matter systems, such as quantum spin chains and one-dimensional electronic models, e.g. the Hub-bard and Kondo models, and models relevant for quantum optics, such as the quantum Rabi and Jaynes-Cummings models. Furthermore, we shall touch briefly on the ongoing quest for a consistent definition of quantum integrability.

Abstract: Quantum entanglement is that when a particle in a system is measured, not only the measured particle, but all the particles of the system, will immediately collapse to the classical result. Quantum entanglement brings bright prospects for the development of new technologies and will create the future quantum earth. Quantum walks are also the result of the entanglement of coins and position spaces, exhibiting very different characteristics than classical random walks. Quantum walks can provide exponential speedups compared to classical algorithms in some applications due to iterative shift and coin operators. Here, we mainly discuss two very different applications: fundamental physics and big data analytics. Majorana 1+1 spacetime dynamics and options pricing models with quantum walks show promise for quantum computing.
