“Hello World!” will be everyone’s first program. In the context of quantum computing, this is very different. In quantum computing, implementing superposition and entanglement is akin to writing a hello world program. This blog discusses the implementation of several fundamental quantum gates used in quantum computing. For implementation, I’m utilizing IBM’s Qiskit open-source package and the Python programming language. Please review my earlier blogs on superposition and entanglement, as well as quantum gates and qiskit, before delving into the implementation, assuming you are familiar with or at least have a basic understanding of the Python programming language. Qiskit is an open-source software development kit for working with quantum computers at the level of circuits, pulses, and algorithms. It provides tools for creating and manipulating quantum programs and running them on prototype quantum devices on IBM Quantum Platform or on simulators on a local computer. Before starti...
