Entanglement is a quantum phenomenon that helps make quantum computing different from classical computing. In a quantum computer, entanglement means that a measurement performed on one qubit affects possible outcomes on a different qubit, even if the qubits are far away on the chip. In this video we explore what entanglement means, how to recognize entanglement, and how to create entanglement in a quantum circuit using Qiskit. We will use the notation and intuition for qubit states that we developed in the previous video in this series, What is a qubit?youtube.com/watch?v=HSM1GfukQMI
