Quantum-Dot Cellular Automata (QCA) technology represents a revolutionary approach in nanoscale computing, leveraging the quantum mechanical properties of electrons to encode binary information via ...
(a) The schematic of the fabricated ZnO device. Two-dimensional electron gas is formed between (Mg, Zn)O and ZnO. Quantum dots are formed by applying gate voltage to this two-dimensional electron gas.
In cellular automata, simple rules create elaborate structures. Now researchers can start with the structures and reverse-engineer the rules. Alexander Mordvintsev showed me two clumps of pixels on ...
