N2 - We derive a universal lower bound of actuating energy Es for broadband photon switching by using an uncertainty relation between time and the negative energy density of quantum fields. We find that broadband photon switching between perfect reflection and perfect transmission over a time ts should satisfy Es ≥ frac(ℏ, 6 π ts).
