单选题 The assertion in the third paragraph that quantum mechanics forbids the duplication of unknown quantum bits tends to support the view that
  • (A) the simple classical triplet code used in repetition code would probably fail for quantum error correction
  • (B) the process of copying information in quantum mechanics affects the value of the thing copied
  • (C) computation codes in quantum mechanics tend to be more susceptible to noise than those in classical mechanics
  • (D) quantum mechanics tends to be more limited in its potential applications than classical mechanics
  • (E) quantum mechanics is ill-suited to the problems of error correction
