A changing state of polarization corresponds to charge movement and so is equivalent to a current.

There is also a single state less than maximal knowledge, corresponding to 1 2 3 4.

Hyperdeformed states correspond to an axis ratio of 3:1.

All single-qubit states correspond to a point on or inside a sphere.

As stated above, in the mathematical formulation, the free states correspond to the absolutely continuous spectrum.

The pure states correspond to vectors of norm 1.

Stable states of molecular systems correspond to global and local minima on their potential energy surface.

These states correspond, in part, to the role of grammatical cases in some other languages.

Excited states correspond to those of anyons, with the energy proportional to their number.

For most people with epilepsy, the inter-ictal state corresponds to more than 99% of their life.
