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

$\mathcal N_t$ is the effective channel from A to R\! $\cup$ \! $C_t$ induced by the hole’s own scrambling dynamics up to time t ; $\epsilon_L(t)$ is a dimensionless number in [0,1] , and $t_L$ has units of time. This is a yes-or-no-shaped promise sharpened into a number: either a decoder within $\epsilon$ of perfect exists on the stated resources, or it does not, and $\epsilon_L(t)$ falls, in the regime this article works in, toward zero as t grows past a threshold.
