Many people may not know it, but we live in a time where the first quantum computers have been created - and they're pretty damn cool. Why? Because while regular bits are limited to only two boring values, QBITs can take near infinite values and operate singularly or in harmony with each other. This outstanding property gives rise to a new kind of algorithms (and a lot of fun!). Follow me on a journey from Zuses Z3 computer and Schrödingers cat to supercooled quantum processors and parallel universes - no PhD in physics required.

106. use a quantum

did the cat survive?

111. The primary data structures employed in the 49-qubit
simulation required just over 4.5 Terabytes of main
memory to store results,while for the 56-qubit
simulation they required just over 3.0 Terabytes. In
contrast, existing state-of-the-art techniques would
have required 8 Petabytes and 1 Exabyte,
respectively.
