Get an introduction to the key concepts of quantum computing

In this course, we will discuss the motivation for building quantum computers, cover the important principles in quantum computing, and take a look at some of the important quantum computing algorithms.

We will finish with a brief look at quantum computing hardware and the budding quantum information technology industry.

Key concepts will be explained graphically, with minimal mathematics but some deep thinking required.

What topics will you cover?

  • Waves and interference
  • Quantum superposition and entanglement
  • Computational complexity
  • The quantum Fourier transform
  • Shor’s algorithm for factoring large numbers
  • Grover’s algorithm
  • Quantum chemistry and machine learning
  • Physical phenomena as quantum bits (qubits)
  • Quantum computing hardware and architecture
  • Quantum error correction
  • The quantum information technology industry

Where did you first hear about quantum computers? DISCUSSION


Let’s begin by talking about the motivation.


In early, 2017, the Google quantum computing research team published a viewpoint article in Nature claiming that commercial quantum systems would be available within 5 years, focusing on quantum simulation (quantum chemistry).


One of the most important concepts you must grasp to understand quantum computing is the superposition and interference of waves.


As a summary of the lesson, let's share your opinion.

Material Includes

  • Official Certificate

Target Audience

  • Anyone interested in quantum computing at the “popular science” level.
  • High school students, college students, and computer professionals interested in developing a qualitative understanding of quantum computing in order to understand the future of computing will benefit.
  • We recommend that you be comfortable with exponents, vectors, sine waves and the basic concepts of probability. There are some equations, but we have endeavored to keep them as few and clear as possible.
  • While the mathematics is not too hard, some concepts will be new to most learners, and require some mental stretching. Be prepared to exercise your brain!
