CMOS technology over Transistor is an important contribution in Very Large Scale Integrated technique for the last two decades. Quantum Dot Cellular Automata (QCA) brings as a replacement solution to the fundamental limits of CMOS technology. This paper is a proposal of making Quantum dot cellular automata (QCA) based Nano-calculator. In this Calculator we've simulated four basic operations: addition, subtraction, multiplication and division. QCA is an advance technology which overcomes some limitations of CMOS such as switching speed. QCA generated circuits operates in the order of terahertz frequency range where circuits does not require any extra power supply for operation.
