The phrase "a small superposition" is correct and usable in written English.
It can be used in contexts related to physics, quantum mechanics, or any discussion involving overlapping states or conditions.
Example: "In this experiment, we observed a small superposition of states that contributed to the overall outcome."
Alternatives: "a minor overlap" or "a slight combination".
An assumption built into NeGOI is that grip aperture can be measured from the superposition of a small number of prototypical hand shapes corresponding to predefined grip-aperture sizes.
Conformational transitions of protein structures can often be approximated by superposition of a small subset of the predicted normal modes (96).
At least at first, however, superconductors had a fatal weakness: Environmental noise, even from the electronics used to control them, can disrupt their quantum superpositions in a small fraction of a microsecond.
Because of the large search space, current methods for protein structure alignment must trade precision for speed and explore only a small but representative set of superpositions.
This is just a small selection of the work in Superposition: Equilibrium & Engagement and there are two more venues too: 4A in the Haymarket, and the Opera House.
Unlike apposition eyes, where the lenses each form a small inverted image, the optical elements in superposition eyes form a single erect image, located deep in the eye on the surface of the retina.
If the error from being off a small fraction of a degree from the original superposition is too much, one could simply re-optimize the conformer superposition provided by PubChem, as the benefits in terms of the ease of storage are considerable.
Pairwise superposition on each subdomain indicates a small average root-mean-square (r.m.s).
Using the superposition principle, Ma and Selim (1994) found that a small pulse BTC contained as much information on solute transport as a large pulse BTC.
A superposition of amplitudes of this type is called a wave-packet state, and its amplitude is usually localized in a small region of the excited-state potential energy surface of the molecule.
