Entangled photons on a chip could lead to super-fast computers

Photon entanglement is one of the odder properties of quantum physics, but it promises a lot for computing — if one photon can instantly affect another no matter how far away it is, you could make super-speedy computers and communications that aren’t easily limited by physical distances. It hasn’t been easy to get entanglement tech down to a manageable size, however, and that’s where Italy’s Università degli Studi di Pavia might just come to the rescue. Its researchers have developed a tiny emitter that could pump out entangled photons as part of an otherwise ordinary silicon chip. The device, which uses a ring shape to both rope in and emit light, measures just 20 microns across. That’s hundreds of times smaller than existing devices, which are comparatively gigantic at a few millimeters wide. You probably won’t see whole processors built around this technique, at least not for a while. Chip makers usually work on the nanometer scale — Intel’s new 14nm processors are far more intricate than this ring. Moreover, there’s some refinement left to make sure this part produces a reliable stream of tangled photons. If everything falls into place, however, you could see entanglement rings boosting performance in certain tasks. You might also see an entanglement-based component that handles jobs which aren’t otherwise possible, like spy-proof quantum cryptography . This breakthrough isn’t going to change semiconductors overnight, but it could make quantum computing more of a practical reality.

Your BMW just downloaded a security patch

Have a BMW, Mini or Rolls Royce with the ConnectedDrive feature parked in your driveway? Maybe all three? Well, it turns out there was a bug that allowed ne’er-do-wells to manipulate it — entirely wirelessly. According to Reuters , by simulating a fake phone network researchers at German outfit ADAC (essentially Deutschland’s AAA) were able to gain access to systems governed by the platform’s SIM card by spoofing a cell tower. They’ve even put together a video describing the gap in security which you can check out after the break — if you speak German. While the vulnerabilities didn’t include anything related to steering, acceleration or braking, the ConnectedDrive does have access to traffic information, air conditioning and… door locks. For its part, BMW says it hasn’t seen any reports of compromises to vehicle security, and now it’s using HTTPS to encrypt all data transmissions. Perhaps best of all? Owners of the 2.2 million affected vehicles didn’t need to hit the dealership for this patch — it was already delivered over the air. The update pushed automatically once the system connected to BMW’s servers recently, but those who keep a car stored may want to hop in and hit the “Update Services” button. Good thing, because taking all three of your rides in for service (like they did in 2012 to fix a problem with the ODB port that thieves actually used to steal cars , and as of 2014 were still using on unpatched vehicles) would probably be kind of inconvenient. Affected models: BMW 1 Series Convertible, Coupé and Touring (E81, E82, E87, E88, F20, F21) 2er Active Tourer, Coupé and Convertible (F22, F23, F45) 3 with Convertible, Coupe, GT, Touring and M3 (E90, E91, E92, E93, F30, F31, F34, F80) 4p Coupe, Convertible, Gran Coupe and M4 (F32, F33, F36, F82, F83) 5 Series GT and Touring (F07, F10, F11, F18) 6 Series Gran Coupe Convertible (F06, F12, F13) 7 Series (F01, F02, F03, F04) I3 (I01), I8 (I12) X1 (E84), X3 (F25), X4 (F26) X 5 (E70, F15, F85), X6 (E71, E72, F16, F86), Z 4 (E89) Mini Three-door and five-door hatchback (F55, F56) Rolls Royce Phantom Coupe and Drophead Coupe (RR1, RR2, RR3) Ghost (RR4) Wrait (RR5) [Image credit: BMW – AFP/Getty Images, control unit – ADAC / Uwe Rattay] Filed under: Transportation Comments Source: Reuters , BMW , ADAC (German)

Tesla’s long-delayed Model X SUV is testing in California

It may look like a Prius that’s been vomited on by Mad Max, but the vehicle you see in the clip below is probably Tesla’s long-delayed Model X SUV . You see, when companies begin stress-testing vehicles, they dress them down with a dodgy paint job and go riding out a deserted airfield, like the one at the old naval base in Alameda. No amount of weird paint, however, could disguise the latest all-electric vehicle to roll off the production line, especially one as long-awaited as the X. It’s been a long road, getting from there to here. The Model X was originally announced back in 2012 , but by the start of 2014, issues with the battery meant the date was pushed back to early 2015. Then, back in November , Elon Musk revealed that the company was having difficulty mass producing components for the falcon-winged vehicle, pushing the launch date back to the tail-end of 2015. If the company is feeling bullish enough to let its high-riding whip out in public, then perhaps he’ll make that deadline. It looks like, despite the heftier build, that the Model X will still be mightily fast, let’s just hope that the company puts Insane Mode as a button right on the steering wheel.

Tesla Model S is getting even quicker through a software update

If you didn’t think that Tesla’s Model S P85D was bonkers enough , you’re in for a treat. Elon Musk has revealed that the already speedy electric sedan is getting a software update that will improve its 0-60MPH acceleration time by a tenth of a second, to 3.1 seconds. That may not sound like much, but that makes the Model S as quick off the mark as McLaren’s MP4-12C supercar. The ‘regular’ P85 will also get a boost, Musk says , although it won’t be “quite as much.” No, this won’t be news to aftermarket tuners used to wringing out more performance through code, but it’s fun to think that a factory firmware upgrade could be the key to winning a drag race.

Amazon put $1.3 billion into Prime Instant Video last year

Amazon may have surprised Wall Street by how much sales went up in the fourth quarter of last year ($29.3 billion, with a profit of $214 million), but for customers its Prime service is the big deal. Founder and CEO Jeff Bezos said Prime membership in the US grew by 50 percent last year, despite a price hike . That growth probably explains (and helps justify) the expanding number of services it’s tacked on to what was originally just an offer of free / cheap shipping. According to Bezos, Amazon plowed $1.3 billion into Prime Instant Video alone in 2014, snapping up exclusives, content from HBO and creating award winning programming like Transparent . [Image credit: Shutterstock] Of course, since this is Amazon there’s no exact number of Prime subscribers revealed, but the company apparently spent “billions” on shipping for the program. The company’s Fire phone didn’t seem to merit much discussion, but for now Wall Street is happy and customers keep clicking that Buy button, so why rain on the parade?

Google X Labs made synthetic skin to test a cancer-detecting bracelet

If someone asks you to name a Google X Labs moonshot, you’d probably say Glass , self-driving car or maybe even Project Loon . But as you might remember from the WSJD Live conference last year, it also has a flourishing Life Sciences division that employs 100 doctors and scientists, and one of their main projects is a Fitbit-like bracelet that can detect cancer cells . Now, The Atlantic has taken a peek into the division’s headquarters in Mountain View. The publication’s video (below the fold) also explains why the team has to create synthetic human skin mixed with the real thing to cover disembodied arms. See, those arms serve as testers for the Labs’ cancer-detecting bracelet project. For that to make sense, though, you need to understand how the system works: first you’ll need to take pills packed with nanoparticles that circulate throughout the body looking for cancer cells. If they find any, they’ll bind to those cells, which then literally light up. After that, the cell-particle combos make their way underneath the bracelet, since it has a magnet that attracts the nanoparticles. Since the team wants to make sure that an illuminated clump of cancer cells is visible through human skin, they created those practice arms. They’re covered in skin exhibiting different properties (thickness, etc.), as well as skin mimicking those of different ethnicities and skin tones. The bracelet probably won’t be sniffing out cancer in the real world anytime soon, though, so watch the interview for now to see what it’s like inside Google X Labs’ Life Sciences department.

Government raked in $44.9 billion from wireless auction

The FCC’s latest wireless auction brought in far more money than anyone expected. The Chairman, Tom Wheeler, set a goal of raising $10.6 billion by selling off 1, 600 licenses to blocks of wireless spectrum. In the end, the government not only blew past its goal, but also its previous record of raising $19.1 billion in 2008, when it auctioned off significant pieces of the 700Mhz band that delivers LTE for a number of carriers. This auction ended with the government raising $44.9 billion, which surprised many observers, especially since even smaller markets like Portland, ME received sizable bids worth tens of millions of dollars. Who won which pieces of spectrum in the 1, 700Mhz and 2, 100Mhz bands is unknown right now, but we do know that 70 different companies and organizations submitted bids. Obvious players were involved, like AT&T and Verizon, but Dish also participated, as did some private equity firms, like Grain Management LLC. Interestingly, Sprint sat this one out, though the company does have what the Wall Street Journal calls , “largest stores of spectrum” in the industry. Part of the reason people were shocked by the high price tag, is that these higher frequencies are actually considered less valuable than lower bands. That’s largely because they’re unable to cover as much distance or penetrate buildings as easily. But, since they’re able to carry large amounts of data over short distances, they can be very useful in cities. Hopefully we’ll have more information about who won what soon, but for now lets just enjoy the cash windfall for the government and the American tax payer.

Microsoft’s new Outlook apps for iOS and Android promise higher productivity

Microsoft has released new Outlook apps for iOS and Android, and they might just be light-years better than those web apps the company has unleashed in the past. See, these are the result of Redmond’s Accompli acquisition in December, and seeing as we liked that startup’s email app when we test drove it last year, we have high hopes for these new ones. The company says the new Outlook for the mobile platforms comes with a built-in calendar and makes attachments easier to add for higher productivity. They’re apparently more tightly integrated with Office apps and Outlook for desktop, as well. We can’t say whether they’ll truly blow your current email apps out of the water as we haven’t tested them yet, but you can find out for yourself by downloading either (or both) from iTunes or Google Play . Take note that the Android app’s just a preview at the moment, so Microsoft could still tweak its features for the final version. Filed under: Cellphones , Mobile , Microsoft Comments

PlayStation is getting a Spotify-powered music service, closing Music Unlimited

Sony today revealed PlayStation Music, a new Spotify -powered music service coming to PlayStation 3, 4 and “Xperia smartphones and tablets” this spring. The service will outright replace Music Unlimited, the service that Sony previously implemented across devices, powered by its own enormous music catalog. The news marks the first time Spotify has come to any game console, and is a major coup for Sony’s PlayStation group in the battle for major home entertainment apps on game consoles (Xbox One notoriously got HBO Go first). PlayStation Music will require a Spotify paid subscription (the “Premium” membership), and enables both playback on the aforementioned devices and the ability to listen to music in the background during games. When the service launches at some point in Spring 2015, it’ll be available in “41 markets around the world.” There are no images/video of the service in action just yet, nor is there news of exactly how pricing will work. We do know the exact date that Music Unlimited will go away, though: March 29, 2015. Sony says that paid users who are still signed up as of February 28th will receive free access through the end of the run. It’s not clear how, or if, their accounts will transfer over to PlayStation Music, but we’d bet they won’t given the tie to Spotify’s accounting system. In case it weren’t clear, this is great news: Music Unlimited is, to put it politely, hot garbage. Here’s what we said about it in our review of the PlayStation 4 : “Music Unlimited is, unbelievably, the only option for playing music on the PlayStation 4. You can’t set up a media server, or play MP3s or audio CDs. There’s a free 30-day trial to the subscription service as part of buying a PS4, but it’s a cumbersome hassle if you’re not already a member. And why can’t we play our own music on this super-powerful PC-esque game console? Sony says more options are coming, but at launch this is your only option. Music Unlimited takes a shockingly long time to load, and navigation within the app is similarly sluggish. When you’ve finally located music you’d like to listen to, you can thankfully push the Home button and keep listening to it on a system level. Jump into a game and turn off the game’s music track — voila! It’s pretty slick, but that same feature existed in a smarter form on the Xbox 360. And on the 360, we could load our own music onto the box.” That was one of the few massive negatives in an otherwise overtly positive console review. Glad to see it’s been sorted! We’ll have more coverage of PlayStation Music as the year rolls on. Filed under: Gaming , Household , Software , HD , Mobile , Sony Comments Source: Sony PlayStation , Spotify , Sony PlayStation EU

The Big Picture: 3D Paris apartment shows what Unreal Engine 4 can do

See that room above? It looks real, but it’s not — and by that we mean it’s just a 3D environment made in Unreal Engine 4. Sure, we already have a pretty good idea what the new engine can do, such as bringing realistic skin (among other things ) to games. But this “Unreal Paris” project by CG designer Dereau Benoît proves that it can be used to create objects and environments that look more like photographs of the real thing rather than CG. Benoît has created a snazzy Parisian apartment with receiving rooms, dining area, kitchen, bedroom, hallways and even a full bathroom. Benoît didn’t skimp on the details: the walls and ceilings are rich with patterns, there’s sunlight flooding in through the open windows, and you’ll see shadows, textures and even reflections mimicking their real-life counterparts. He took down the demo he uploaded on his website (presumably to iron out the kinks), but you can watch a video of the tour below to see what kind graphics to expect in future games.
