Basic Introduction to Quantum Computing

Quantum computing for everyone.

Dr. Chuck Easttom

This is an introduction to quantum computing meant for those in IT, cybersecurity, and related fields who might not have substantial math or physics background. The concepts will be explored with minimal mathematics. This would include basic concepts, the use of the Bloch sphere, quantum superposition, and quantum gates. Particular attention will be paid to practical applications such as the impact on cryptography and security, Quantum resistant cryptography and the NISTIR 8240.

Quantum computing is fast approaching a practical reality. QC impacts the future of computing as well as security issues. QC will render current asymmetric cryptographic methods insecure. That requires QC resistant algorithms. IT personnel and cybersecurity professionals must have at least a basic conceptual understanding of quantum computing.

What you'll learn-and how you can apply it

  • Understand conceptually quantum computing
  • Have a fundamental understanding of quantum gates
  • Know the impact of QC on cybersecurity and cryptography
  • Understand the basics of quantum resistant cryptography

This training course is for you because...

  • IT personnel (programmers, network admins, etc.) can gain an understanding of quantum computing without having an extensive physics and math background.
  • The impact of QC on IT and cybersecurity is so significant that all professionals in these fields need to have at least a working knowledge.
  • It is a prerequisite for more advanced training.


  • None. This is meant for those without a relevant background.
