Entanglement and superposition are key principles of quantum mechanics from "summary" of Quantum Supremacy by Michio Kaku
Entanglement and superposition, the two key principles of quantum mechanics, are what set this field apart from classical physics. Entanglement is the phenomenon where particles become correlated in such a way that their states are connected, even when they are separated by vast distances. This means that the state of one particle can instantly influence the state of another, regardless of the physical space between them. Superposition, on the other hand, allows particles to exist in multiple states simultaneously. These two principles form the foundation of quantum computing, which harnesses the power of entanglement and superposition to perform computations at speeds that are unimaginable with classical computers. In a classical computer, bits are used to represent information as either 0 or 1. However, in a quantum computer, qubits can exist in a superposition of both 0 and 1 at the same time, exponentially increasing the co...
