description Overview

W state

In quantum information science, a W state is a specific type of multipartite entangled quantum state involving three or more qubits. For three qubits, it is defined as a superposition where exactly one qubit is in the excited state while the others are in the ground state. The W state is highly notable because it retains bipartite entanglement even if one of its particles is measured or lost to th...

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...
