Quantum LDPC codes with positive rate and minimum distance proportional
to n^{1/2} [PDF]
Jean-Pierre Tillich, Gilles ZemorThe current best asymptotic lower bound on the minimum distance of quantum LDPC codes with fixed non-zero rate is logarithmic in the blocklength. We propose a construction of quantum LDPC codes with fixed non-zero rate and prove that the minimum distance grows proportionally to the square root of the blocklength.View original: http://arxiv.org/abs/0903.0566
