Quantum Information Theory (QIS) is a further abstraction of a abstract model of real-world physics.


  • QIS was first suggested by Richard Feynman as a means to model the real quantum work of subatomic interactions in Information Theory.

Three Areas of QIS

These area were taken from Hoofnagle and Garfinkel's book[1]

Quantum Sensing

Quantum Communication

See the wiki page on the Quantum Computing Threat to existing cryptography.

Quantum Computing

  • Most closely tracks the original suggest from Richard Feynman in modeling the physical reality of Quantum Mechanics.
  • Note that some would place the Quantum Computing Threat in this category as well. Any taxonomy such as this runs into classification ambiguity.
