human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "a decoding algorithm for css codes using the x z correlations"):
  Abstract: We propose a simple decoding algorithm for CSS codes taking into account the correlations between the X part and the Z part of the error. Applying this idea to surface codes, we derive an improved version of the perfect matching decoding algorithm which uses these X/Z correlations.

Includes members:
  Member "an application of khovanov homology to quantum codes":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "on tensor products of css codes")
  Member "quantum ldpc codes with positive rate and minimum distance proportional to the square root of the blocklength":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "pseudocodeword based decoding of quantum stabilizer codes")
  Member "quantum error correction beyond the bounded distance decoding limit":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "distance verification for classical and quantum ldpc codes")
  Member "a construction of quantum ldpc codes from cayley graphs":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "distance verification for classical and quantum ldpc codes")
