Scientists create quantum entanglement on a silicon chip

A team of scientists has figured out a way for a standard silicon chip to tackle quantum entanglement — a phenomenon in which multiple particles are connected to each other and act in uniform, regardless of how far apart they are. The scientists’ findings were detailed on Monday in a research paper published in Optica, a monthly journal by The Optical Society (OSA).

So far, harnessing the power of quantum entanglement onto silicon chips has proven to be a difficult task because of the large size of the devices used to emit entangled photons; photons are essentially the particles that make up light. Creating silicon chips — which are inexpensive and prevalent compared to specialized entanglement equipment — that can handle quantum entanglement is a big deal in that it can allow for more powerful computer chips and better encryption technology.

The researchers of Università degli Studi di Pavia in Italy have come up with a way to solve this problem by creating a microscopic device that can supposedly fit onto a silicon chip and produce entangled photons.

The researchers paired a silicon wafer with what’s known as a ring resonator — a closed loop that photons enter on one side via a laser beam. They emerge entangled on the other side, where they are captured.

According to the research paper, the team of scientists was able to “demonstrate that silicon ring resonators in a silicon-on-insulator platform are an efficient source of time-energy entangled photon pairs.”

From the research paper:
[blockquote person=”” attribution=””]We can confidently expect that silicon mircoring resonators will become the dominant paradigm of correlated photon sources for quantum photonics, both for applications involving the transmission of quantum correlations over long distances, such as quantum cryptography, and for applications involving quantum information processing “on-a-chip.”[/blockquote]

Quantum entanglement can be very useful to the field of security and can help with encrypting messages. GridCOM Technologies, for example, explained to Gigaom in 2013 that it uses quantum entangled photons to generate encryption keys.

Any time someone tries to measure an entangled photon to learn what it may have encrypted, the GridCOM system is automatically pinged because of the way the photons are connected; each entangled particle affects the other and when one particle exists in a state where it is spinning up, its correlated particle will take on a state where it is spinning down.

Cisco buys vCider to boost its distributed cloud vision

vCider’s virtual networking smarts will help Cisco build distributed cloud infrastructure that ties into its own Open Networking Environment. The move is seen as a counter to VMware’s acquisition of Nicira.

UFC Demands Justin.tv and Ustream Give Up Pirates’ IP Addresses

The UFC is looking to crack down on illegal live streams of its pay-per-view events, subpoenaing live streaming sites Justin.tv and Ustream to get the IP addresses needed to identify and shut down users that have made videos of those events available for free online.

Fisker & DOE Loan Delays Deal Blow to Quantum

It’s no secret that Quantum Fuel Systems Technologies Worldwide (s QTWW) is betting big on plug-in hybrid vehicle startup Fisker Automotive — the green car startup’s genesis was built on a vision of having the well-known luxury car designer Henrik Fisker design a vehicle around a Quantum drivetrain. The risk of that bet comes out loud and clear in Quantum’s latest earnings report, which covers the company’s financial results for the first nine months of the 2010 fiscal year.
Quantum’s revenue sank to just $1.5 million in the third quarter of fiscal year 2010, down from $5.9 million in the same three months of 2009. For the first nine months of fiscal year 2010, revenue dropped to $7.2 million, down from $17 million in the year-earlier period. According to Quantum’s earnings statement, discussed in a call with shareholders this morning, “The decrease in revenue for the third quarter and first nine months of fiscal 2010 is primarily related to delays at Fisker Automotive related to the Fisker Karma development program.”

Solar Roof Maker Asola Forms Manufacturing JV

The moon roof was the must-have feature of yesterday, but the necessary automotive accessory of tomorrow could be the solar roof. German Asola, maker of solar power systems for automotive applications (including solar roofs for cars), announced today that it has signed a memorandum of understanding to form a joint venture with Korean electronic and automotive component maker Q&Tech / Yongsan to establish a solar module manufacturing plant in South Korea with an annual capacity of 30 megawatts. The plant will use Asola’s solar production processes and will give Asola a partner that already has strong ties to the auto industry.

Asola is 25 percent owned by Quantum Technologies, an automotive technology developer that has moved away from its gasoline engine pursuits and is now the drivetrain provider for the Karma plug-in hybrid luxury vehicle from Fisker Automotive, in which it is a major stakeholder.

And yes, the Karma will sport a solar roof from Asola, which will power a climate-control system to keep the $80,000 four-door sports car cool when parked in energizing sun, ’cause that leather interior can get hot sitting in a parking lot.

Christmas remote controlled webcam

Alek’s Christmas Lights Webcam

Use the christmas webcam to view live images of a buncha christmas lights and also CONTROL them – i.e. YOU can turn them ON and OFF via your web browser! The christmas webcam has PAN and ZOOM capability that you can also control. The webcam and webcontrol are ONLY operational between 1800 and 2200 Mountain Time. Each web surfer can only update the webcam 10 times, change the lights 3 times, and play with the pan/zoom 5 times, within 5 minutes – this limits the load on my server/Internet connection and I’m concerned about the christmas webcam being (ab)used too much and the blinking lights bothering the neighbors! 😉
