N2 - Recently, there arose a problem of 'quantum string,' which is a linelike object meandering quantum-mechanically and undergoes entropy-reducing collisions with adjacent neighbors. In this paper, we overview underlying physics of the quantum string, and report our simulation result on the collision-induced entropy loss of a quantum string between walls by means of the density-matrix renormalization group.
