Abstract - Quantum computers are the next great
Finally, the paper discusses the importance, advantages, and disadvantages of quantum computers, emphasizing the need to understand the challenges of traditional computing to fully appreciate the potential of quantum technology.
technology that will take over the world, because of it applications on difficult problems related to the classical computers. The proposed work attempts to create an ALU using the quantum technology and its circuits using quantum gates. The ALU performs 7 qubit operations in the local simulator and also the same is executed on the cloud on the using the quantum computer hosted by IBM. Analysis is carried to find the differences between the simulator output and the quantum computer output. Here a 16 qubit ALU capable of performing all the arithmetic and logical operations is also built, that executes on the simulator. The simulator locally replicates the properties of quantum computer on local system.
2. BACKGROUND Classical computers use bits that represent either 0 or 1, while quantum computers use qubits, which can exist in superpositions of states, representing both 0 and 1 simultaneously. Each state in a superposition has an associated amplitude, a complex number that differs from the positive probabilities in classical computing. By manipulating these amplitudes, quantum algorithms can amplify correct answers and cancel out incorrect ones, offering a significant speed advantage over classical computers for certain problems.

1.INTRODUCTION
Quantum computing power increases exponentially with the number of qubits, unlike the linear relationship between transistors and processing power in classical computing. Quantum computers excel in tasks like optimization, data analysis, and simulations, whereas classical computers are better suited for everyday processing tasks
Quantum computing is an advanced form of computing rooted in quantum mechanics, combining principles from physics, mathematics, computer science, and information theory. It offers significant advantages over classical computers, such as higher computational power, lower energy consumption, and exponentially faster processing, by manipulating microscopic particles like atoms, electrons, and photons.
3. OBJECTIVE The main objectives of our proposed system are as follows:
This paper introduces quantum computing, beginning with the evolution of traditional computing and the limitations that have led to the development of quantum technologies. It explains the basic concepts of quantum computing, including key quantum properties like superposition, entanglement, and interference. The paper also explores the architecture, hardware, software, design, types, and algorithms specific to quantum computers, highlighting their potential impact on areas such as cybersecurity, traffic optimization, medicine, and artificial intelligence. While small-scale quantum computers are currently being developed, ongoing research suggests a promising future for this technology.
