"Rather than shunting qubits through the quantum analogue of the logic gates found in regular computers, it translates problems into a landscape of hills and valleys. D-Wave's qubits explore this landscape to settle on the lowest energy state, which corresponds to the solution. For this to work, the qubits must be cooled as close to absolute zero as possible – the chips are housed in a custom fridge the size of a small room.
However, critics said it wasn't clear the energy-landscape approach would provide an advantage, and had doubts that D-Wave's computers are properly quantum."
