Quantum+Physics

Quantum Physics Quantum Physics, A.K.A quantum mechanics, is a scientific theory that helps scientists understand how the building blocks of everything (electrons, protons, quarks and anything else at the subatomic level). Quantum mechanics has many real-world applications, such as quantum computers, which instead of relying on transistors (tiny switches that can be turned on and off) like a digital computer, they instead rely on superposition, a quantum principle that says an atom can be in two states at once, for example a switch that can be both on and off.
