Why is the scientific community skeptical about D-Wave developments?

Question

On May 11, 2011, the D-Wave One computer was introduced, based on a 128-qubit processor. But this news (like the previous ones) did not receive a wide resonance due to the fact that (I quote from the wiki): “The Canadian company D-Wave announced in February 2007 that it had created a sample of a quantum computer consisting of 16 qubits (the device was called Orion ). Information about this device did not meet the requirements of a reliable scientific report, so the news did not receive scientific recognition. Moreover, the company's future plans - to create a 1024-qubit computer in the near future - caused skepticism among members of the expert community.
What requirements do not meet under -quantum computers / processors from D-Wave ( recently sold one )? Why are they not recognized?

Answer 1

Here, for example, is an interesting link to an article in CT , where experts discussed the issue.

Answer 2

Because D-Wave One is not a quantum computer.
The guys from D-Wave implemented the logic of a quantum computer based on qubits. There is nothing revolutionary here. Any intelligent person who knows discrete mathematics and circuitry can assemble a 2-bit or 4-bit qubit.
To create a D-Wave quantum computer, there is not enough implementation of the technical component - quantum teleportation. But this task is much more difficult.
