Observations on Hyperplane: II. Dynamical Variables and
... question is yes. But I asked my questioner if he agreed that his question was analogous to asking, within non-relativistic quantum theory, another question. That question is whether an observable at a given time could always be expressed as a function of observables at the time, t = 0, and whether, ...

The choice of basis is a matter of convenience. • Similarly, a quantum code is best thought of not just as a collection of codewords, as in classical codes, but as a subspace P of the Hilbert space Hc of the code carriers, a su ...

Mutually Unbiased bases: a brief survey
... for all i, j, r 6= s. This leads to our first and most important definition: Definition 1.3. Let B1 = {|ϕ1 i , ..., |ϕd i} and B2 = {|φ1 i , ..., |φd i} be orthonormal bases in the d-dimensional state space. Then they are said to be mutually unbiased if and only if | hϕi |φj i | = √1d for all i, j. ...

This operator is exceptionally important as its eigenvalues and eigenfunctions are the "energy levels" of the system, and it is transitions between these energy levels which are detected in spectroscopy.
