description Overview

W state

A W state is a specific entangled quantum state where each qubit has an equal probability of being in either the |0⟩ or |1⟩ state, and all are correlated to be different.

density matrix

The density matrix is a mathematical tool used in quantum mechanics to represent the state of a quantum system. It accounts for both known and unknown components within that state, including mixed states resulting from interactions or entanglement. This formalism provides a way to describe open systems – those interacting with their environment – where a definite pure state cannot be defined. Dens...
