Ever wanted to understand how quantum computers work – and what they may imply for our future, being that their processing power could be great enough to model and to create simulations of the universe? You’re in luck, because this excellent video by Aussie YouTuber ColdFusion makes it easy to understand.
Quantum mechanics is a field of physics that studies the behavior of the most basic and smallest parts of our universe, at the subatomic level. Reality at this level is very different from the reality we experience day-to-day but it is reality, nonetheless.
In the quantum world, things are always happening in a superposition, where particles can be in more than one state at the same time. Classical computers use bits, which are either a “0” or a “1” to process information but if we use quantum particles as data, something interesting happens. By using quantum particles called qubits and the property of superposition, they can read both as a “0” or a “1” – at the same time
