A polarized petahertz current is driven by an ultrashort laser in an organic superconductor. This is in contrast to the common sense belief which is justified by Ohm's law, i.e., a net current cannot be induced by an oscillating electric field of light. The current enhances near the superconducting transition temperature. The light-driven petahertz current opens a way to high-speed operation of computers which is one million times faster than conventional ones.
