Let us consider a particle trapped in an infinite square well, that is, confined in the interval 0 < x < Οa, and also in the PΓΆschl-Teller family (9.1) viewed as regularizations of such an infinite potential.
We describe in a unified way universal operations for quantum systems with arbitrary finite dimension and show some links among them. In particular, we discuss a connection between optimal universal cloning and optimal state estimation. We then describe the operation of the depolarising quantum chan
Operator bases are discussed in connection with the construction of phase space representatives of operators in finite-dimensional spaces, and their properties are presented. It is also shown how these operator bases allow for the construction of a finite harmonic oscillatorlike coherent state. Crea
