1 Theories of quantum mechanics (which are still used now) were outlined in detail.
2 Theories about a neural network model were published.
… a textbook outlining the theories (The Principles of Quantum Mechanics [3]) was published in 1930; it is still in use.
The neural network model is based on a 1949 book by Donald Hebb (The Organization of Behaviour: A Neuropsychological Theory [1]) which outlines the relationship between different neurons and how these create intelligence.
3 The nearest neighbour algorithm was developed.
4 The idea of quantum computers was suggested for the first time.
A good example of these is the nearest neighbour algorithm, first conceived in 1967, …
The idea of developing quantum computers is not a new one, but practical developments are relatively recent. It was first suggested by Richard Feynman in 1981, …
5 A quantum computer was offered for sale for the first time.
The first commercially available quantum computer was offered by D-Wave Systems in 2011.
