1. Intro to QCA / Operation of majority gate
	In order to model MQCA devices, Dr. Lei He (EE) will develop circuit models to accurately model traditional CAD metrics, such as area, power and delay. The ability to fabricate so-called zero-dimensional structures in which a few electrons can be artificially confined offers new possibilities for conceiving quantum computation at the nanometer scale [1].Recent experiments have shown that quantum dot atoms can be placed in close enough proximity to form quantum dot molecules [2].  One emerging technology based on interacting quantum dot molecules is quantum cellular automata (QCA). 
	The basic building block of QCA is the quantum dot molecular cell, illustrated in Figure 1.
