Introduction
Quantum entanglement is a fundamental phenomenon in quantum physics where two or more particles become correlated in such a way that the quantum state of each particle cannot be described independently.
Mathematical Description
The state of an entangled system can be written as:
\[|\psi\rangle = \frac{1}{\sqrt{2}}(|0\rangle_A|1\rangle_B - |1\rangle_A|0\rangle_B)\]This is known as a Bell state, one of the simplest examples of quantum entanglement.
