Quantum skeptics now predict a working computer in 10 years

Do quantum computers exist? It depends who you ask. D-Wave, the Canadian company that has repeatedly sold alleged quantum computers to the likes of Google and Lockheed, says yes — it’s not a particularly robust implementation, but according to them the world does, in principle, have a quantum computer today. Others, however, are not so sure, and several high-profile studies have been produced calling both the speed and the true quantum nature of the chip into question.

Now, however, two prominent quantum skeptics have authored a paper saying that the technology is finally approaching a point they believe is capable of true quantum computing. The study, published on arXiv, uses as an example problem, the issue of electron distribution in complex materials. If we could simulate electron distribution and movement quickly and accurately, in full detail, the researchers say computers could start making much more powerful guesses about how doc create complex new superconducting hybrid materials, among other things.

The incredible size of the possibility space of this problem is impossible for classical computers to usefully handle — but this paper claims that a quantum computing architecture could get the job done in as little as 10 years. The crux of the issue, in their eyes, is the ability to control quantum phenomena. So-called “small” quantum computers, with a limited number of logical quantum bits (“qubits”) could be possible fairly soon, but their size means they’re only capable of addressing simple quantum questions.

Their way around this is to suggest a hybrid quantum computing architecture that incorporates quantum capabilities into a more typical super-computing system. A relatively inaccurate approximation algorithm is actually good enough to predict for the vast majority of electron orbitals in complex materials, so the team proposes using existing computers for this problem. The remaining electrons, which are held in much more complex ways and subject to greater uncertainty about their likely locations and behavior, can be predicted with a much more precise algorithm that requires quantum-level speed to finish in a reasonable amount of time.

Electrons are very difficult to map in strongly correlated materials.

By leveraging the advantages of both classical and quantum computing, we could see real advances in the science of electronic simulation. The system would be designed from the ground up to deal with this particular problem — not a comprehensive programmable computer, but one built to purpose. That’s not all that different from early classical computers, which were created to tackle specific problems. An eventual generalized quantum operating system could put the speed of quantum computing to use for anything user desires.

That’s a long way off, however. D-Wave’s supposedly quantum chip runs at just above absolute zero, and requires a shielding apparatus the size of a small room. Even if we can create real quantum computers, we’ll need to do so without those drawbacks if we want the technology to work its way into consumers’ homes. It could possibly work its way into consumers’ lives more quickly by selling computational time on a quantum computer and streaming it into a screen, serving thousands or tens of thousands of customers with a single quantum rig, but that would require much better high-speed internet infrastructure than currently exists.
