In this talk, I will present recent work on computing flux tube entanglement entropy (FTE²), the finite entanglement entropy attributable to the flux tube, in 1+1D and 2+1D SU(N) Yang-Mills theories. I will review analytical results in 1+1D and show numerical results from lattice simulations in 2+1D. These results will be compared to expectations from effective string models, highlighting points of agreement and notable deviations. I will explore how FTE² depends on the representation of static charges, the effective and intrinsic width of the flux tube, temperature, and the number of colors N_c. I will also discuss preliminary results from ongoing lattice studies and their implications for the quantum structure of the flux tube, as well as future directions.
