D-Wave, a Canadian company, recently released a supposed commercial, 128-qubit quantum computer. If their claims are true, then the computer, called the D-Wave One, would be a quantum leap forward for computing. A 128-qubit computer can represent all of the 3.4*10^38 128-bit numbers simultaneously, which would require an incredible amount of normal computing power. The D-Wave One should have the potential to change the world in profound ways. Several of these systems running in parallel should be able to accomplish feats requiring incredible computing power – simulations of proteins, the search for extraterrestrial life, and other tasks would become much easier to accomplish.
However, I am skeptical about the true quantum nature of the computer. My first sign of suspicion is the fact that no other researchers have even come close to running a viable quantum computer. Other research teams have been unable to use more than fourteen-qubit computers, and are unable to maintain the quantum states of the qubits for a useful number of operations. A 128-qubit computer would be orders of magnitude more difficult to sustain. It is possible that D-Wave has discovered some incredible breakthrough that enables them to create such a machine, but if the best other top scientists have been able to do is a quantum computer with fewer than fourteen bits, it seems unlikely D-Wave has managed to create a 128-qubit quantum computer. Indeed, other top scientists are highly suspicious of the D-Wave One’s quantum nature.
Another fishy aspect of the D-Wave One is its specialization. A true computer should theoretically be able to harness its processing power to accomplish any computable task, but the D-Wave One only claims to solve specialized math problems. It also claims that it cannot yet outperform conventional computers, which seems absurd considering that the system should be able perform 3.4*10^38, or three-hundred and forty undecillion, operations in a single step, which is far, far beyond the ability of computer in the world. So why isn’t this computer able to outperform a conventional computer with only a fraction of this capacity?
Finally, there is a strangely small amount of press coverage for such a supposedly world-changing invention. The revolutionary nature of a 128-qubit computer should cause it to make far more headlines than it has, and this lack of coverage is also suspicious.
However, the D-Wave One has its believers. D-Wave’s first customer is Lockheed-Martin, who bought a computer for $10 million after analyzing it for a year. They must have found enough certainty through their analysis to warrant the hefty price tag, which leads me to suspect that even if the computer does not work as well as advertised, there still might be something revolutionary about it. The size of Lockheed-Martin’s commitment reflects their certainty. If the D-Wave One is really a legitimate quantum computer, it could profoundly change the world, but its true nature remains to be confirmed.
