When Quantum Computers Break Reality - Explained

This video goes over the possible future of quantum computers, as well as simply explaining how they work, why Albert Einstein thought the quantum world was 'spooky', what Brian Cox has to say, and explains the concepts of quantum superposition, entanglement, and decoherence, and how quantum computers are different vs. normal computers.

The video also goes over why quantum particles cannot be used for instant, faster than light, communication - say between Earth and Mars (because of the no communication theorem).

Further out in the future, quantum computer technology will be used to create simulations of humanity, and even the entire Universe. These machines will allow humanity to look back in time, simulating the big bang, asking the question, what happened before? And what about advancing humanity's understanding of black holes, could it be possible for universes to be born within these mysterious cosmic bodies.
