Open-air quantum teleportation performed across a 97km lake

' Sending signals through fiber optic cable is reliable and fast, but because of internal absorption and other effects, they will lose photons—which is a problem when the number of photons being sent is small. This is of particular concern in quantum networks, which typically involve a small number of entangled photons. Direct transmission through free space (vacuum or air) experiences less photon loss, but it's very difficult to align a distant receiver perfectly with the transmitter so that photons arrive at their destination. A group in China has made significant progress toward solving that problem, via a high accuracy pointing and tracking system. Using this method, Juan Yin and colleagues performed quantum teleportation (copying of a quantum state) using multiple entangled photons through open air between two stations 97 kilometers apart across a lake. Additionally, they demonstrated entanglement between two receivers separated by 101.8km, transmitted by a station on an island roughly halfway between them.



However, quantum communication sometimes also requires coordination between two distant receivers, so the researchers set up the transmitter on an island in the lake. The receivers were 51.2 and 52.2 km from the photon source respectively, on opposite shores of Qinghai lake, forming a triangle with the transmitter. The distance between the receivers—101.8km—was far enough to create a 3 microsecond delay between measurements of the photon polarization.

Given this setup, there was no possible way for the two receiving stations to communicate. Yet the photons they registered were correlated, indicating entanglement was maintained.

These experiments provide not only a proof of principle for free-space quantum communication, but also a means to test the foundations of quantum theory over larger distances than before. With very large detector separation, quantum entanglement experiments can help differentiate between standard and alternative interpretations of the quantum theory. Though the long-distance aspect is promising, the fact that they set up on the shores of a lake (where no intervening obstacles exist) and that the experiment could only be performed successfully at night indicate its limitations. Author Yuao Chen told Ars via e-mail that they are working on solving the problem for daytime communication, but since the signal consists of single photons, it's not clear how this will work—the number of received photons fluctuated with the position of the Moon, so noise appeared to be a significant problem for them. Point-to-point communication will need to solve that problem as well before satellite-to-ground quantum networks are practical. '

quantum teleportation

I am losing it with this. Sounds like magic. If this engineers out, are we looking at wireless transmission of data in volume? Where does it lead?

"demonstrated entanglement between two receivers separated by 101.8 km"

This is phenomenal, Jim.

Regardless of imminent practical applications (or not) with this successful test, it validates some profound insights into quantum theory. Like any new piece of evidence substantiating scientific theories, who can say what it could lead to. Likewise with the recent discovery of the Higgs particle.

If we lose the wonder of discovery and relegate all our actions to bottom line effectiveness, we lose our humanity.

Martian Computing Is Light on RAM, Heavy on Radiation Shielding

"But down on Earth, bit flipping is something that’s taken very seriously by the scientists like Geist, who run massive supercomputers. These systems fill up huge amounts of memory — a large target for the cosmic rays — and they run precise calculations that simply can’t have any errors.

And without the radiation hardening techniques cooked up by people such as Sridharan, these supercomputers simply wouldn’t work."

Tiburon, the Town Where They Always Know Your Name
from Reason.com Full Feed by J.D. Tuccille
In what is the most detailed article about license-plate scanners that I've seen to-date, Ars Technica starts with a report on how up-scale Tiburon, California, scans every car that transits the two roads into town, and then discusses the legal ramifications and potential risks of the technology. It's really an excellent piece and well worth a read to gain a good grasp of where we're likely to go as plate scanners pop up hither and yon, and what that's likely to mean for our privacy in terms of enhanced law-enforcement, government intrusions and abuses.

For starters, Cyrus Farivar writes:

Tiburon, a small but wealthy town just northeast of the Golden Gate Bridge, has an unusual distinction: it was one of the first towns in the country to mount automated license plate readers (LPRs) at its city borders—the only two roads going in and out of town. Effectively, that means the cops are keeping an eye on every car coming and going.

A contentious plan? Not in Tiburon, where the city council approved the cameras unanimously back in November 2009.

The scanners can read 60 license plates per second, then match observed plates against a "hot list" of wanted vehicles, stolen cars, or criminal suspects. LPRs have increasingly become a mainstay of law enforcement nationwide; many agencies tout them as a highly effective "force multiplier" for catching bad guys, most notably burglars, car thieves, child molesters, kidnappers, terrorists, and—potentially—undocumented immigrants.

There's a high creepy factor for those of us inclined in that direction, but the town boasts of some benefits that we'll have to take at face value.

Cronin explained that in a town like Tiburon, where the biggest criminal concern is property crime, knowing who is coming and going at odd hours has been very helpful to the squad. The chief added that, prior to deploying the cameras, crime was still relatively low—only about 100 to 120 thefts per year, he said. Since the cameras have been in place, that figure has dropped by "around a third," he said.

For intelligent, systematic criminals, I can easily see how license-plate scanners would be a deterrent. So would any intrusive tracking technology. Still, the town's police concede the risks.

[T]he system is not without flaws. It tends to yield numerous false positives because the hot list data received from the California Department of Motor Vehicles takes a long time to be updated—and because the system cannot distinguish out-of-state plates. This creates a problem if, for instance, California plate ABC123 has been reported as stolen and is on the hotlist, and then someone drives through Tiburon with Oregon plate ABC123. (Other LPR systems can distinguish the plates from different states.) ...

And he recognizes the system's easy susceptibility to abuse. "We could put our boss's plates in the system and every time she leaves town we could go get her golf clubs," he joked.

To prevent problems, only Cronin and Hutton can add plates to the hot list. Each time a plate is run for historical data by either an officer or requested by an outside agency, the requester has to inform the chief by e-mail. Requests are tallied in an annual report for the town council.

Elsewhere, as the article details, false positives have had some unpleasant outcomes. including a woman ordered out of her car at gunpoint in San Francisco in a stop later upheld by the courts. And license-plate tracking has also helped solve crimes, including a murder in New York.

As I've written and said on television, I have serious concerns about this technology. I have no doubt that it can help solve crimes. The same could be said of random home searches. But I think the dangers and likely abuses outweigh any potential gains.

But go read the Ars Technica piece and decide for yourself.

U.S. WIND ENERGY PRODUCTION AND MANUFACTURING SURGE
Aug 15, 2012 11:58 AM

The Energy Department released a new report yesterday highlighting strong growth in the U.S. wind energy market in 2011. According to the 2011 Wind Technologies Market Report, the United States remained one of the world’s largest and fastest growing wind markets in 2011, with wind power representing 32 percent of all new electric capacity additions in the United States last year and accounting for $14 billion in new investment. According the report, the percentage of wind equipment made in America also increased dramatically. Nearly 70% of the equipment installed at U.S. wind farms last year – including wind turbines and components like towers, blades, gears, and generators - is now from domestic manufacturers, doubling from 35 percent in 2005.

The report finds that in 2011, roughly 6,800 MW of new wind power capacity was added to the U.S. grid, a 31 percent increase from 2010 installations. The United States’ wind power capacity reached 47,000 MW by the end of 2011 and has since grown to 50,000 MW, enough electricity to power 13 million homes annually or as many as in Nevada, Colorado, Wisconsin, Virginia, Alabama, and Connecticut combined. The country’s cumulative installed wind energy capacity grew 16 percent from 2010, and has increased more than18-fold since 2000. The report also finds that six states now meet more than 10 percent of their total electricity needs with wind power.

The growth in the industry has also led directly to more American jobs throughout a number of sectors and at factories across the country. According to industry estimates, the wind sector employs 75,000 American workers, including workers at manufacturing facilities up and down the supply chain, as well as engineers and construction workers who build and operate the wind farms.

Technical innovation allowing for larger wind turbines with longer, lighter blades has steadily improved wind turbine performance and increased the efficiency of power generation from wind energy. At the same time, wind project capital and maintenance costs continue to decline, driving U.S. manufacturing competitiveness on the global market. For new wind projects deployed last year, the price of wind under long-term power purchase contracts with utilities averaged 40 percent lower than in 2010 and about 50 percent lower than in 2009, making wind competitive with a range of wholesale power prices seen in 2011.

Despite these recent technical and infrastructure improvements and continued growth in 2012, the report finds that 2013 may see a slowing of domestic wind energy deployment due in part to the possible expiration of federal renewable energy tax incentives. The Production Tax Credit (PTC), which provides a tax credit to wind producers in the United States, is set to expire at the end of this year. Working in tandem with the PTC, the Advanced Energy Manufacturing Tax Credit provides a 30 percent investment credit to manufacturers who invest in capital equipment to make components for clean energy projects in the United States.
