Divincenzo Criteria

The DiVincenzo Criteria, introduced by David DiVincenzo in 1996, are a set of conditions necessary for a qubit modularity to build a quantum computer.

The following are necessary for quantum computation:

  • A scalable physical system with a well-characterized qubit
  • The ability to initialize the state of the qubits to a simple fiducial state
  • Long relevant coherence times
  • A “universal” set of quantum gates
  • A qubit-specific measurement capability

    • The following are necessary for quantum communication:

  • The ability to interconvert stationary (used for storage and processing) and flying (used as messengers) qubits
  • The ability to faithfully transmit flying qubits between specified locations
