How Many Qubits does the D-Wave 2000Q Have?

Each D-Wave 2000Q QPU is fabricated with 2048 quantum bits (qubits) and 6016 couplers.


Of this total, the number of devices, and the specific set of devices, that can be made available in the working graph changes with each system cool-down and calibration cycle. Calibrated commercial systems typically have more than 97% of fabricated qubits available in their working graphs. Yields significantly higher than this are not guaranteed.

Properties of the current online system can be found here.
