Quantum physics is the study of the frankly downright bizarre world of atoms and subatomic particles, such as neutrons, photons, and electrons. At these microscopic levels, time can be "negative" and particles can exist in two places at the same time – think: Schrödinger's cat – thanks to a concept known as superposition.

Another peculiarity observed at the subatomic level is quantum entanglement. When two or more particles become entangled, they share a connection that persists even across mind-bogglingly vast distances. This means that measuring one instantly affects the state of the other, no matter how far apart they are.
