Abstract: Quantum-dot fabrication and characterization is a well-established technology, which is used in photonics, quantum optics and nan electronics. Four quantum-dots placed at the corners of a square form a unit cell, which can hold a bit of information and serve as a basis for Quantum-dot Cellular Automata (QCA) nan electronic circuits. Although several basic QCA circuits have been designed, fabricated and tested, proving that quantum-dots can form functional, fast and low-power nan electronic circuits, QCA nan electronics still remain at its infancy. One of the reasons for this is the lack of design automation tools, which will facilitate the systematic design of large QCA circuits that contemporary applications demand. Here we present novel, programmable QCA circuits, which are based on crossbar architecture. These circuits can be programmed to implement any Boolean function in analogy to CMOS FPGAs and open the road that will lead to full design automation of QCA Nano electronic circuits. Using this architecture design and simulation of QCA circuits have proved to be area efficient, stable and reliable.
