Big Data + Quantum Computing = AI?

Leave a comment

Everything that is currently sold as Artificial Intelligence is in fact, statistics. Sure, it’s a very advanced (and capable!) form of statistics called Big Data^, but still, it’s just statistics. Machine Learning is entirely human-written algorithms that chew data.

The so called “AI” is, unfortunately for us, not intelligent at all^ – and I say unfortunately not because I know AI won’t be hostile towards us (at least not by intent^), but rather because the current form of “AI” is defined and shaped by the hands of humans, who are experts at wiping each other out.

In any case, Machine Learning is powerful.

Electricity costs is one example of how corporations get an edge over each other using Machine Learning:

This is, of course, a nice win for Google. Now let’s see when the technology will make life better for the rest of the planet, not only for the corporation’s shareholders (and partners).

Another clever use of Machine Learning is materials research:

Of course, ML is also becoming instrumental in medicine. That’s one of the most interesting fields for ML since there’s heaps of interesting data just lying to be put to (hopefully) good use:

But all this is still using good old transistors. And transistors might soon look like a horse & carriage compared to what quantum computers will be capable of (even though the two will no doubt have synergies fueling their co-existence for a while):

Here’s a nice summary covering a lot of things surrounding the upcoming quantum computing revolution:

Sure, quantum computers won’t immediately be used to run Crysis^, but they are clearly set to allow an even greater leap in computational power than the one we already experienced during the past 66 years of transistor-based computation^.

And it’s not just about computational power, but also security & speed. Here’s an article about quantum communication:

The race for quantum supremacy is on. For updates, follow this page:

So what will happen when we reach, and then dive deep into quantum supremacy and bring all our Big Data tech to that depth? I once read an article that said “A.I. still needs us — to build quantum computers”. Here, I found it:

And here’s a bonus article: a leaked internal Google video shows a creepy vision of how data could be used to direct human decision-making. And keep in mind that this was on Google’s design table already several years ago:

We Don’t Live in a Computer Simulation (Is That a Good Thing?)

Leave a comment

Every now and then, somebody is amazed at the ever-increasing power of computers to simulate reality. The accuracy of these simulations increases every year, in step with the increase in computing power. This has led some to extrapolate that eventually we will reach the ability to simulate an entire Universe, perhaps even including conscious beings. And if so, what if we’re a simulation ourselves? According to new research, this is, in principle, impossible due to, you guessed it, the most mysterious of phenomena: quantum effects.

The article above presents this as good news. For me, this is neither good nor bad news. Actually, thinking of myself as a simulated object never dulled my sense of reality, nor my respect for life. And besides, if I’m simulated then perhaps there are some mighty creatures watching over my destiny. What I experience right now sure doesn’t feel fake so I couldn’t care less about the technology behind it. In any case, theories come and go and who knows what the future holds? Probably not even the simulators ;).

Quantum Supersampling

Leave a comment

It’s been quite some time since the last major breakthrough in computer graphics. For the past few decades, graphics quality has been steadily improving, but this has been mainly due advances in semiconductor technology and secondly due to software evolution. Little has changed when it comes to the way images can be efficiently rendered. Ray-tracing^ has been around for a while but it is too computationally-intensive to match rasterisation^.

At long last, an evolutionary leap might soon be upon us thanks to quantum computing. There are myriad applications for this emerging branch of technology, but one of the most interesting I’ve learned about lately is this fascinating proposal called quantum super-sampling. It’s a process combining ray-tracing with quantum computation. Here’s a (long) video presentation describing the process, by the author himself:

https://vimeo.com/180284417^

Eric Johnston is quite well known in the computer graphics world. Seeing such a proposal from him fills me with enthusiasm. It might take a decade or more for this technology to become mainstream, but when it happens – when, not if – we will witness a major improvement in graphics rendering, possibly leading to real-life quality video games and experiences.

Combined with the instant transfer of information that is made possible by quantum entanglement, this might mean that a powerful central server could render realistic graphics for a very large number of people. Perhaps us becoming capable of projecting universes might be proof that this Universe is a projection?
