Recent understanding of Quantum Science and Technology has exceeded our expectations for meeting the requirements of human society for different applications, such as telemedicine, in the 21st century. Free-space optical (FSO) communication is one of the key technologies for realizing ultra-high-speed multi-gigabit-per-second (multi-Gb/s) large-capacity communications. Using lasers as signal carriers, FSO laser communications (Laser-Com) can provide a line-of-sight, wireless, high-bandwidth, communication link between remote sites. Rapidly growing use of the internet and multimedia services has created congestion in the telecommunications networks and placed many new requirements on carriers. IR Laser transmitters offer an intermediate low risk means to introduce desired network functionalities with extremely high bandwidth, over conventional RF wireless communications technology, including higher data rates, low probability of intercept, low power requirements, and much smaller packaging. Spintronics as another emerging field for the next-generation quantum devices using the Spin degree of freedom of Electrons /Holes, Neuromorphic engineering, etc. Nature offers us a full assortment of atoms, but Quantum engineering is required to put them together in A SMART an elegant way to realize functional structures not found in nature ON OUR PLANET EARTH. A particular rich playground for Quantum era, is the so-called semiconductors, made of different atoms from the periodic table, and constituting compounds with many useful optical and electronic properties. Guided by highly accurate simulations of the electronic structure, modern semiconductor quantum devices are literally made atom by atom using advanced growth technology to combine these ATOMS INTO materials in SUCH ways to give them new proprieties that neither material has on its own. Modern mastery of atomic engineering allows high-power and highly efficient functional Quantum devices to be made, such as those that convert electrical energy into coherent light or detect light of any wavelength and convert it into an electrical signal. This historical conference will present the future trends and latest world-class research breakthroughs that have brought quantum Science and Technology to an unprecedented level, creating light detectors and emitters over an extremely wide spectral range from deep UV TO THZ (0.2 to 300 microns), as well as their integration with Si photonics. Inspiring by Nature, to find solution to fight with power of nature against human life!
