Furthermore we prove that a graphical quantum code over a finite field is a stabilizer code. The technique used in the proof establishes a new connection between quantum codes and quadratic forms. We provide some simple examples to illustrate our results.5 pages, 2 figures, paper presented at the 2002 IEEE International Symposium on Information TheoryQuantum PhysicsInformation Theorytext
