The concept of quantum simulations was proposed by physicist Richard Phillips Feynman in 1981, and quantum simulations become possible by manipulated ultracold atoms. In 1995, Bose-Einstein condensation was realized and degenerate fermi gas in 1999. The first BEC-BCS Crossover quantum simulation experiment was carried out in 2003 by using the Fermi Gas. In 1998, Austrian scientist Peter Zoller ...

Microfabrication and integration technologies are fundamental supporting technologies to the novel micro/nanoscale electronic device and the micro/nano-electro-mechanical system (M/NEMS), which drive the development of microelectronics and M/NEMS. In the past several years, we focused on the silicon-based micro/nanofabrication and integration technologies and explored new processes for a variet...
