Qubit, An Intuition #1 — First Baby Steps in Exploring the Quantum World
The beauty of Quantum Mechanics for Quantum Computation, featuring IBM Quantum

TL;DR;
- The intuition of a quantum bit (qubit) as a computing unit in a Quantum computer, in comparison to a binary digit (bit) in a Classical computer.
- Bra-ket notation, bloch sphere, hybrid Classical-Quantum.
- The source code (in Python) for generating illustrated qubit state transitions is available on github.
- This is the first article in the "Qubit, An Intuition" series. Upcoming articles (towards the end of 2021) will discuss "Inner Product, Outer Product, and Tensor Product", "Quantum Measurement", "Unitary Matrices", "Quantum Circuit and Reversible Transformation", as well as "Quantum Algorithms."
For an introductory helicopter view of the overall six articles in the series, please visit this link “Embarking on a Journey to Quantum Computing — Without Physics Degree.”
Five years ago — a new, first in the world Quantum computer services announced for public access, accessible through the Cloud. Thanks to IBM for the generosity to share the future of the computing revolution in the 21st century. Physicists, scientists, and the general public, including myself with no formal education background in Physics and without direct involvement in building Quantum computers, have enjoyed the access since.
In May 2016, IBM introduced a 5-qubits Quantum computer (with Quantum assembly language to interact with the Quantum computer) through the IBM Cloud. By early 2021, there have been 26 Quantum computers with 1, 5, 7, 15, 16, 27, 32, and 65-qubits configurations. Moreover, we expect that a 127 qubits Quantum computer will be available in 2021, followed by 433 qubits in 2022 and 1,121 qubits in 2023.
In addition, the IBM Qiskit framework has supported Python’s higher-level programming language since 2017. IBM contributed Qiskit to open-source.
