In order to construct quantum [[n,0,d]][[n,0,d]] codes for (n,d)=(56,15)(n,d)=(56,15), (57,15)(57,15), (58,16)(58,16), (63,16)(63,16), (67,17)(67,17), (70,18)(70,18), (71,18)(71,18), (79,19)(79,19), (83,20)(83,20), (87,20)(87,20), (89,21)(89,21), (95,20)(95,20), we construct self-dual additive F4F4-codes of length nn and minimum weight dd from circulant graphs. The quantum codes with these parameters are constructed for the first time.
