Quantum dot cellular automaton

Quantum Dot Cellular Automaton (QDCA) is a computational model that uses arrays of quantum dots as basic units to perform computations. In this model, each quantum dot represents a binary state (0 or 1) and can interact with its neighboring dots, similar to how cellular automata operate. ### Key Features of Quantum Dot Cellular Automaton: 1. **Quantum Dots**: These are semiconductor particles that are small enough to exhibit quantum mechanical properties.
