# What's a Qubit on D-Wave 2000Q?

From D-Wave flyer:

The D-Wave 2000Q system has up to 2048 qubits and 5600 couplers. To reach this scale, it uses 128,000 Josephson junctions, which makes the D-Wave 2000Q QPU by far the most complex superconducting integrated circuit ever built.

How do they define Qubit? Are these Qubits build an universal quantum computer? Does D-Wave satisfy DiVincenzo's criteria?
