Simultaneous Measurement
... The Hamiltonian formulation of classical mechanics is erected upon the notion that dynamical variables occur in conjugate pairs {q, p}—a notion which leads naturally (via the Poisson bracket) to the more general concept of conjugate observables. Heisenberg’s early efforts led Born (1926) to the real ...

Localizing multiple excitations is far more complicated, because the number of states exponentially increases with the number of excitations. However, at least for a one-dimensional qubit system, by tuning n one can obtain a long “localization ...
