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

A density matrix represents the state of a quantum system in a form that can describe both pure states and mixed states. A pure state can be represented by a single state vector, while a mixed state involves a statistical mixture. The density matrix allows both cases to be handled within one mathematical framework and supplies the information needed to calculate measurement probabilities and expec...
