# How to Create a Quantum Binary Adder

In this project, we’ll create a quantum circuit to perform the addition of qubits. This circuit will not only implement the quantum counterpart of a classical binary adder but will also allow the leveraging of quantum phenomena like quantum superposition for arithmetic operations.

You will learn to:

Create and simulate a quantum circuit using Qiskit

Understand the concept of quantum parallelism

Perform arithmetic operations on qubits

Visualize the results of quantum simulation using dedicated packages

Project Description

Quantum computing is a new technological field that involves the use of quantum phenomena to perform computations. This non-conventional approach to computation has its advantages over classical technology–a phenomenon known as quantum supremacy. While efforts are underway to create a general-purpose quantum computer, current quantum technologies are already finding applications in cybersecurity, finance, and communication.

In this project, we’ll be implementing a quantum binary full adder. As the technology for implementing classical and quantum logical circuits is different, the design for a quantum binary adder will have marked differences from its classical counterpart. Therefore, instead of going for the usual sum-of-product approach to implement the binary logic, we’ll adopt a heuristic approach for finding the gate combination.
