In the new work, researchers show how to factor an integer of any size with a single qubit and three components known as oscillators — readily available devices typically associated with other quantum technology, like optics systems.

Graphically, this can be represented a little better if ∅ symbolizes the empty set:
0 = ∅
1 = {0} = {∅}
2 = {0, 1} = {∅, {∅}}
3 = {0, 1, 2} = {∅, {∅}, {∅, {∅}}}
Zermelo has thus laid the foundations for integers.
