Exact Minimum Distance of a [[832,10]] Quantum LDPC Code: d = 15 by Exact Fold and Lift Enumeration
We determine the exact minimum distance of a two block quasi cyclic CSS code with 832 physical and 10 logical qubits. Earlier work had shown 10 ≤ d ≤ 15. We close the interval and prove d = 15. In eac...
