A quantum lattice representation (QLA) is devised for the initial value
problem of one-dimensional (1D) propagation of an electromagnetic disturbance
in a scalar dielectric medium satisfying directly only the two curl equations
of Maxwell. It si found that only 4 qubits/node are required. The collision,
streaming, and potential operators are determined so as to recover the two curl
equations to second order. Both polarizations are considered.Comment: 11 pages, 10 figure
