Random access codes have provided many examples of quantum advantage in communication, but concern only one kind information retrieval task. We introduce a related task—the Torpedo Game—and show that it admits greater than the comparable random code. Perfect strategies involving prepare-and-measure protocols with experimentally accessible three-level systems emerge via analysis terms discrete W...
