WebF are orthonormal, the von Neumann entropy (defined as S = Trfrˆ lnrˆg) may be easily found: SM = n å k=1 l k lnl k. (11) In what follows, we will show that the entropy to the mixed state (field), Equation (10), is equal to the entropy associated with a virtual atom and will verify that this fact is consistent with the WebThe entropy of entanglement (or entanglement entropy) is a measure of the degree of quantum entanglement between two subsystems constituting a two-part composite quantum system.Given a pure bipartite quantum state of the composite system, it is possible to obtain a reduced density matrix describing knowledge of the state of a subsystem.
