Quantum computer

From Tardis Wiki, the free Doctor Who reference

A quantum computer, or Feynman computer, was an advanced computer that operated at the quantum level. Rather than binary, i.e. ones and zeros, yes or no, a quantum computer essentially worked on the principle of Schrödinger's cat, i.e. yes and no at the same instance.

The Plath and Lurlak were species using quantum computers for thousands of years before humans, (PROSE: The Quantum Archangel) who tried developing a Feynman computer in the 21st century sometime after 2022. (AUDIO: The Uncertaintiy Principle)

The De-mat Gun possessed a quantum computer linked to the Homeworld's causal nexus. (PROSE: The Book of the War)
