Quantum Dot Cellular Automata

A much-required breakthrough in the field of VLSI took place with the birth of Quantum-dot cellular automata (QCA) technology, an impressive amalgamation of Quantum Physics and Nanotechnology and acted as a possible replacement to the age-old semiconductor transistor-based designs (CMOS) with Boolean paradigm. In this paper, we aim at implementing this technology to build a robust 8:1 multiplexer that can help in building and developing many more digital logic circuits, from an already proposed 2:1 multiplexer. It has excellent efficiency with respect to least cell count, latency, space and power dissipation.

Quantum-dot cellular automata (QCA) are nanoscale digital logic constructs that use electrons in arrays of quantum dots to carry out binary operations. In this paper, a basic building block for QCA will be proposed. The proposed basic building block can be customized to implement classical gates, such as XOR and XNOR gates, and reversible gates, such as CNOT and Toffoli gates, with less cell count and/or better latency than other proposed designs.
