摘要：

We show, on four-dimensional Minkowski spacetime, that [psi/T(mu-nu)/psi], the renormalized expectation value in a general quantum state [psi] of the stress-energy tensor for electromagnetism, satisfies the averaged-null-energy condition, i.e., that integral d-lambda[psi/T(mu-nu/psi]t(mu)t(nu) greater-than-or-equal-to 0 where this integral is along complete null geodesics with an affine parameter lambda and tangent vector t(mu).
