# Does the D-Wave 2000Q satisfy DiVincenzo's criteria?

DiVincenzo's criteria for quantum computation are the following:

1. A scalable physical system with well characterized qubits.
2. The ability to initialize the state of the qubits to a simple fiducial state.
3. Long relevant decoherence times.
4. A “universal” set of quantum gates.
5. A qubit-specific measurement capability.

Are they satisfied by the D-Wave 2000Q?

This was originally part of this question but is better suited to be a separate question.

## 1 Answer

No, as point 4 is not satisfied.

The D-Wave machines are quantum annealers and thus not universal.

See this question on how to make from the D-Wave machine a universal quantum computer.
