Double slit experiment
Light source behind wall with two narrow closely spaced slits.
Photosensitive plate on other side
!
Light waves overlap and interfere with each other. Same amplitude = reinforcement Different amplitude = cancel each other out
With single photons the same happens! Photons are in superposition between two paths Possibilities interfere with each other
What is a quantum computer?
Classical Bits = 0 or 1 Quantum Computer uses qubits = superposition between 0 and 1 -> Variables that have all possible values at the same time!
