Abstract: The uncertainty principle of quantum mechanics could be the most profound discovery of modern physics. Its implications are wide ranging, from philosophy of science to engineering. The underlying mechanics that lead us to the uncertainty principle also lead us to entanglement — a joint property of multiple particles that says ‘you will get pure randomness, unless you observe a coupled system using a coupled observation’. This simple rule — unique to the quantum world — can be engineered to transform the way we calculate, via a quantum computer, and the way we communicate, via quantum cryptography.
