lower bound: | 5 |

upper bound: | 5 |

### Construction

Construction of a [[13,0,5]] quantum code:
[1]: [[13, 0, 5]] self-dual quantum code over GF(2^2)
cyclic code of length 13 with generating polynomial w^2*x^12 + x^11 + x^10 + w*x^9 + w^2*x^8 + w*x^6 + 1
stabilizer matrix:

### Notes

- All codes establishing the lower bounds where constructed using MAGMA.
- Most upper bounds on qubit codes for
*n≤100* are based on a MAGMA program by Eric Rains.
- For
*n>100*, the upper bounds on qubit codes are weak (and not even monotone in *k*).
- Some additional information can be found in the book by Nebe, Rains, and Sloane.
- My apologies to all authors that have contributed codes to this table for not giving specific credits.
