Comment Limitations of D-Wave's Computer (Score 2) 39

I thought the article had a fairly succinct criticism of D-Wave's computer:

Since 2009, Google has been testing a machine marketed by the startup D-Wave Systems as the world’s first commercial quantum computer, and in 2013 it bought a version of the machine that has 512 qubits. But those qubits are hard-wired into a circuit for a particular algorithm, limiting the range of problems they can work on. If successful, this approach would create the quantum-computing equivalent of a pair of pliers—a useful tool suited to only some tasks. The conventional approach being pursued by Microsoft offers a fully programmable computer—the equivalent of a full toolbox. And besides, independent researchers have been unable to confirm that D-Wave’s machine truly functions as a quantum computer. Google recently started its own hardware lab to try to create a version of the technology that delivers.

Submission + - Microsoft's Quantum Mechanics

catchblue22 writes: MIT Technology Review has an excellent article summarizing the current state of quantum computing. It focuses on the efforts of Microsoft and Alcatel-Lucent's Bell Labs to build stable qubits over the past few years.

In 2012, physicists in the Netherlands announced a discovery in particle physics that started chatter about a Nobel Prize. Inside a tiny rod of semiconductor crystal chilled cooler than outer space, they had caught the first glimpse of a strange particle called the Majorana fermion, finally confirming a prediction made in 1937. It was an advance seemingly unrelated to the challenges of selling office productivity software or competing with Amazon in cloud computing, but Craig Mundie, then heading Microsoft’s technology and research strategy, was delighted. The abstruse discovery—partly underwritten by Microsoft—was crucial to a project at the company aimed at making it possible to build immensely powerful computers that crunch data using quantum physics. “It was a pivotal moment,” says Mundie. “This research was guiding us toward a way of realizing one of these systems.”

Let's see: total number of Ebola Patients in the U.S. is ... 1. Mssr. Duncan is dead and cremated and no longer spreading the disease. So, the answer is "no".

You didn't bother reading the summary or the article, did you? Not just 1, Mr. Duncan. The next victim is the trained, well-equipped health care professional who - despite having far better protection and awareness than the vast majority of people in the world - just tested positive for having caught the virus from him.

What's your point in ignoring that glaring little dose of reality?

In the US, more poeple have died of gunshot wounds in the last month than have died from Ebola since it was discovered. Let's not talk about rational, effective responses from conservatives.

Yes, and far more people die every in the US from being beaten to death by killers using fists and blunt instruments than have died by killers using rifles of any kind, let alone the small number that involved scary looking rifles with black plastic parts on them. So what? Someone deciding to kill someone else - with a knife, a pipe, a gun, or their bare hands - isn't nearly as common as stupid kids killing themselves and others in cars, but mostly: it's an active decision. There's no comparing that to an outbreak of an ugly infectious disease, especially one with a high mortality rate that can kill you weeks after pick it up from someone's spit on a doorknob.

You want rational responses to both topics? OK, don't let violent criminals out of jail. Don't tolerate the existence of violent gangs like MS13 in our cities, and stop making it so politically incorrect to lock up crazy people who are plainly dangerous. And of couse, find ways to reduce one of the largest sources of death-by-gun stats, which is suicide - like, make Oregon's option more widely available. And in the meantime, work globally to stop travel out of West Africa until their outbreak problem is under control.

Yeah, just inject lots of thorium and/or uranium into the core until it starts heating up...

I will assume you are being sarcastic here. Warming the core is pure science fiction IMHO.

By comparison, warming Mars would be relatively easy. Just manufacture large amounts of CFC's and emit them into the atmosphere. They are very strong greenhouse gasses and are relatively persistent, though they won't last forever. Emit enough of these and you may warm Mars up enough to release the frozen CO2 in the ground, which will lead to even more warming. Eventually you may be able to melt the frozen water, which will make life possible.

That isn't to say that this would be easy. You would have to mine fluorine and chlorine and then use a factory to make the gas. But it isn't that difficult. And even with Mars' lack of magnetic field, any atmospheric densification will likely last for millions of years. The MAVEN satellite will give us more reliable information on this.

All this drone stuff will be fine until one manages to crash into an airliner, bringing it down. Then the FAA will be swamped with people demanding to know why the drones were allowed in the first place.

Which is also true of traditional RC aircraft, which have been flown for decades - with plenty of opportunities to get up into the path of full-scale aircraft. The carnage has been incredible, one plane after the next falling out of the sky.

The problem isn't going to be people shooting crop health, checking their gutters, doing an aerial during a TV shoot, or getting real estate photos. The problem is going to be malicious users. Just like wrong-headed people who choose to be malicious with lead pipes, shotguns, or kitchen knives.

A bunch of laws telling law abiding people not to fly their camera robot over 400' will mean exactly nothing to someone who doesn't care about laws.

And what does it have to do with technology?

Regardless of your take on how the editor wrote the headline, the concept here (the government empowering trash collectors to police your behavior after looking through what you throw out) is right there in keeping with the government doing all sorts of other things that involve prying into your behavior with an eye towards controlling it. Technology is the most common or at least a highly visible venue for that sort of intrusion these days, so other blatant examples of government micromanagement (like looking through your trash) serve nicely to remind technologists of the larger underlying issues, and that there ARE such issues.

OK, you got me. For a moment there I thought you were taking yourself seriously, and having a rant, however misguided. It's a shame there's no satire/sarcasm tag to reward you for your sense of humor. That was a good one!

And there is no way to convince me that the state can't defeat them with its little finger

Which state are you talking about? If a state doesn't have a coherent, functional military with the resolve to fight against these guys, then there's nothing else up their sleeves to use. Iraq wasn't ready for this. ISIS just kidnapped another 68 Iraqi soldiers to use as extortion leverage, and has killed a bunch more using suicide bombers. Recent recruits there have no stomach for fighting people like that with only what Iraq has that passes as its own air power for support. Their "little finger" isn't nearly enough to protect and hold the dam in Mosul, for example, let alone stamp this group out of existence.
