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 "on new quantum codes from matrix product codes"):
  Abstract: In this paper, by using matrix product codes, several classes of new quantum codes are obtained. Moreover, some of them have better parameters than the previous quantum codes available.

Includes members:
  Member "quantum codes from generalized reed solomon codes and matrix product codes":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "matrix product constructions for hermitian self orthogonal codes")
  Member "application of constacyclic codes to quantum mds codes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a new method for constructing eaqec mds codes")
  Member "new quantum codes from evaluation and matrix product codes":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "lcd matrix product codes over commutative rings")
  Member "a construction of new quantum mds codes":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "galois hulls of mds codes and their quantum error correction")

The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
