N⊥[Γ]=2πℏ∫Γ[⟨H(τ)⟩−E0(τ)]dτN_\perp[\Gamma] = \frac{2}{\pi\hbar}\int_\Gamma\left[\langle H(\tau)\rangle - E_0(\tau)\right]d\tau

Why this formula appears here

Define the object this paper needs: for a worldline Γ\Gamma traced by a processor, with instantaneous mean energy above its own ground state ⟨\langle H(τ\tau)⟩\rangle - E0(τ)E_0(\tau) measured in the processor’s own comoving rest frame at proper time τ\tau , the cumulative orthogonalization count is N⊥[Γ]=2πℏ∫Γ[⟨H(τ)⟩−E0(τ)]dτN_\perp[\Gamma] = \frac{2}{\pi\hbar}\int_\Gamma\left[\langle H(\tau)\rangle - E_0(\tau)\right]d\tau. N⊥N_\perp[Γ\Gamma] is a real-valued, non-negative functional of a timelike worldline in a fixed background spacetime together with a stated local energy convention; because the integrand is an energy and dτ\tau is a time, the integral has action units and N⊥N_\perp is dimensionless. It is invariant under reparametrizing Γ\Gamma ’s own curve parameter, since only proper time enters, and…
