Introduction and Beginners Guide to Quantum Computing

Abstract

Quantum computing is a fascinating topic, and the authors attempt to give a detailed explanation about the history of quantum computing, double slit experiment, introduction about quantum computers, quantum super position, quantum entanglement, overview about quantum supremacy, building quantum computing, single bit gates, multi-bit gates, model of quantum computing with applications, and case study. The quantum computing was developed using quantum algorithms and quantum devices. Firstly, the quantum algorithms are developed as mathematical models, and the performance is evaluated through simulations, algebraic algorithms (cryptography, Diffie-Hellman, shor algorithm, for RSA) and amplitude amplification (database searching, pattern matching, etc.). Secondly, the quantum devices are the original physical devices built with optical connections instead of electrical connections. The qubit control uses the microwave for superconducting, laser, quantum dots, and photonics (optical instrument).
