    "abstract": "We argue that (first-order) coherence is a relative, and not an absolute,\nproperty. It is shown how feedforward or feedback can be employed to make two\n(or more) lasers relatively coherent. We also show that after the relative\ncoherence is established, the two lasers will stay relatively coherent for some\ntime even if the feedforward or feedback loop has been turned off, enabling,\ne.g., demonstration of unconditional quantum teleportation using lasers.",
