Abstract: After the advent of Quantum Physics, new opportunities were created for research and development in the world of science and technology. Quantum computation is one such emerging technology which allows for notable speed-ups compared to conventional computational methods. Here a quantum bit simulator is presented. This simulator is an engineering work, and no deep understanding of quantum mechanics is required from the user. The well-known phase estimation algorithm is presented using this simulator. The qubit simulator will be a useful tool for the study of quantum computer circuits, quantum computing, and the development of new quantum algorithms
