Characteristics of quantum computers

  • Communication Ability When they physically share entanglement,
    quantum information can be easily transmitted and
    shared with each other.
    Through this, communication complexity
    can be significantly reduced.
  • Calculation Ability By using the superposition, interference, and
    entanglement characteristics of quantum information,
    it is easy to check the global characteristics of
    the data values to be processed, so it shows
    particularly excellent performance in problems
    that require a lot of complex parallel operations.
  • Security Ability The observable collapsibility
    of quantum information, the impossibility of duplication,
    and the randomness of the expression method make
    it possible to use it more diversely than
    the existing method in information protection.
