Submission + - Researchers Send Information Using a Single Particle of Light (vice.com)

Submitted by Anonymous Coward
An anonymous reader writes: According to research published Thursday in Science, physicists at Princeton University have designed a device that allows a single electron to pass its quantum information to a photon in what could be a big breakthrough for silicon-based quantum computers. The device designed by the Princeton researchers is the result of five years of research and works by trapping an electron and a photon within a device built by HRL laboratories, which is owned by Boeing and General Motors. It is a semi-conductor chip made from layers of silicon and silicon-germanium, materials that are inexpensive and already widely deployed in consumer electronics. Across the top of this wafer of silicon layers were laid a number of nanowires, each smaller than the width of a human hair, which were used to deliver energy to the chip. This energy allowed the researchers to trap an electron in between the silicon layers of the chip in microstructures known as quantum dots. The researchers settled on photons as the medium of exchange between electrons since they are less sensitive to disruption from their environment and could potentially be used to carry quantum information between quantum chips, rather than within the circuits on a single quantum chip. The ability to scale up this device would mean that photons could be used to pass quantum information from electron to electron in order to form the circuits for a quantum computer.

Submission + - World's Largest Hedge Fund To Replace Managers With Artificial Intelligence (theguardian.com)

An anonymous reader writes: The world’s largest hedge fund is building a piece of software to automate the day-to-day management of the firm, including hiring, firing and other strategic decision-making. Bridgewater Associates has a team of software engineers working on the project at the request of billionaire founder Ray Dalio, who wants to ensure the company can run according to his vision even when he’s not there, the Wall Street Journal reported. The firm, which manages $160 billion, created the team of programmers specializing in analytics and artificial intelligence, dubbed the Systematized Intelligence Lab, in early 2015. The unit is headed up by David Ferrucci, who previously led IBM’s development of Watson, the supercomputer that beat humans at Jeopardy! in 2011. The company is already highly data-driven, with meetings recorded and staff asked to grade each other throughout the day using a ratings system called “dots”. The Systematized Intelligence Lab has built a tool that incorporates these ratings into “Baseball Cards” that show employees’ strengths and weaknesses. Another app, dubbed The Contract, gets staff to set goals they want to achieve and then tracks how effectively they follow through. These tools are early applications of PriOS, the over-arching management software that Dalio wants to make three-quarters of all management decisions within five years. The kinds of decisions PriOS could make include finding the right staff for particular job openings and ranking opposing perspectives from multiple team members when there’s a disagreement about how to proceed. The machine will make the decisions, according to a set of principles laid out by Dalio about the company vision.

Am pretty happy with sling. A bundle sure, but the bundle contains the 4 or 5 channels that I may ever watch. Easier to flip past 10-15 crap channels than 150 crap channels, especially on the relatively nice Roku interface instead of crappy 1980's cable box interface. Doubt any a la catre option would be cheaper than $20 for those channels anyway. As much as cable channels want you to pay, even free viewers make them money, hence bundles.
