QMASM: A Quantum Macro Assembler (opens in new tab)

It is a common and significant misconception that D-Wave is an "adiabatic quantum computer". Adiabatic quantum computers for instance would be able to factor numbers in polynomial time (or more generally, adiabatic quantum computers have the full power of quantum computation, i.e. they efficiently solve problems in the BQP class). D-Wave, while being an interesting computing machine, is definitely not a general quantum computer (not even they claim that anymore). Moreover, classical computers have proven to be better at the optimization problems D-Wave was specifically designed for.

Calling it a "debate" might be giving too much credit to D-Wave. Nobody, not even they anymore, is claiming that this is a machine capable of more efficient computations than a classical Turing machine (as opposed to a quantum circuit). By "efficient computation" I mean asymptotically polynomial.

Moreover, experimenting with the actual hardware has shown that a classical computer is practically better than this machine (in terms of money, electricity, or time).
