The world's first commercial quantum computer built by D-Wave Systems

I saw a article with the unbelievable title on the EE Times which is "Quantum computer 'Orion' debuts" a couple of weeks ago. It was the incredible news because I thought it would take very long time to build the first commercial quantum computer.
D-wave systems, which is the company in Canada that build the world's first commercial quantum computer, has used the superconducting technology with niobium cooled down near absolute zero to create the quantum states as a qubit. This amazing system is expected to be able to solve the NP-complete problems in a few cycles. What a fabulous achievement, isn't it? Other promising technologies are NMR, optical method like photonic polarization, and silicon technology such as quantum dots.
