Computing Models

• Universal quantum computer:

  • The quantum-circuit or Gate Model will be described in the next chapters.

  • A variant is the measurement-based model playing a main role in the Photonics Quantum Computer Realization.

• Adiabatic quantum computer:

  • The major algorithm run on an adiabatic quantum computer is called Quantum Annealing.

  • This computing model has not of universal purpose, but can be used to solved combinatorial optimization problems.

  • see the chapter devoted to Adiabatic Quantum Computer.

• Topological quantum computer:

  • a not-so-easy-to-grasp approach based on quantum systems living in a 2-dimensional physical space, that would inherently possess a great stability and resistance to noise,

  • still not (or at least not conclusively) experimentally verified,

  • see the chapter devoted to Topological Quantum Computer.
