What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
The reply cannot be a difference in the redundancy number, since by construction the two numbers can be made to agree. It must be a difference in what redundancy costs the source. The classical sensors read a fixed value without disturbing it, so an observer could add a thousand-and-first fragment for free. The quantum construction cannot make that promise: every additional fragment is drawn from a probe that has already interacted with the rotor through , and the paper’s own back-action results predict that competence gained by later fragments should trade against residual orientation asymmetry in the source [ 4 , 3 ] . A classical emulator has no such cost curve to reproduce; its…

A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
