Algebraic quantum theory instead takes the observables as primitive, and the state space is a deri ...

Aspects of quantum information theory
... Quantum information and quantum computation have recently attracted a lot of interest. The promise of new technologies like safe cryptography and new “super computers”, capable of handling otherwise untractable problems, has excited not only researchers from many different fields like physicists, ma ...

An Introduction to the Mathematical Aspects of Quantum Mechanics:
... Quantum States and Observables In classical physics the mathematical description of a phenomenon is somewhat clear. From the early days of modern science, the movement of a macroscopic body could be completely characterized by the specification of its position at a given instant of time. This proces ...

... Relevant to us later, the theory is also time-reversal invariant and (for most states) Poincaré recurrent. That is, for every history there is also the time-reversed history given by the transformations t-t and *; and for every initial condition (x1(0)..xN(0),(0)), the time development by (1) a ...
