Research


Quantum and Nano Computing Systems Research Group focuses on design and performance analyses of emerging information processing paradigms. The group studies physical-information-theoretic aspects of optical and electronic logic circuits with a particular emphasis on fundamental performance efficiency evaluation. The methodology developed by Principle Investigator (PI) Dr. Ercan enables calculation of lower bounds on energy dissipation for digital nanocomputing paradigms with illustrated applications to Nano-Application Specific Integrated Circuits (NASICs) and Quantum-dot Cellular Automata (QCA). The group currently focuses on expanding the breadth of technology bases by developing physical-information-theoretic models for Brownian circuits, optical microring resonator-based logic circuits, solid-state based quantum logic circuits, as well as non-Von Neumann architecture-based processors (such as Artificial Neural Networks). In addition to the theoretical and computer simulation-based research conducted by the group, Dr. Ercan also collaborates with experimental researchers to test the proposed fundamental bounds against practical sources of inefficiency. This research provides solid foundations to asses and compare efficiency limitations of non-conventional post-CMOS technology proposals.
