Storing Photons In a Solid State Device 68

Posted by timothy from the next-year-in-vending-machines dept.
bondisthebest writes in with a report from IEEE Spectrum: "Physicists in Switzerland, led by Nicolas Gisin of the University of Geneva, reported last week in Nature that they have made a solid-state device capable of storing photons for as long as 1 microsecond. The invention will aid in the development of light-based quantum-cryptography networks, which are theoretically impervious to hacking but are currently limited in range to a few dozen kilometers, primarily because of a lack of a suitable way to store the quantum state of photons."

Watergate "Deep Throat" Mark Felt Dead At 95 126

Posted by kdawson from the linda-lovelace-in-mourning dept.
Hugh Pickens writes "W. Mark Felt Sr., 95, associate director of the FBI during the Watergate scandal, better known as 'Deep Throat,' the most famous anonymous source in American history, died at his home in Santa Rosa, California. Felt secretly guided Washington Post reporters Bob Woodward and Carl Bernstein to pursue the story of the 1972 break-in of the Democratic National Committee's headquarters at the Watergate office buildings, and later of the Nixon administration's campaign of spying and sabotage against its perceived political enemies. 'It's impossible to exaggerate how high the stakes were in Watergate,' wrote Felt in his 2006 book A G-Man's Life. 'We faced no simple burglary, but an assault on government institutions, an attack on the FBI's integrity, and unrelenting pressure to unravel one of the greatest political scandals in our nation's history.' No one knows exactly what prompted Felt to leak the information from the Watergate probe to the press. He was passed over for the post of FBI director after Hoover's death in 1972, a crushing career disappointment. 'People will debate for a long time whether I did the right thing by helping Woodward. The bottom line is that we did get the whole truth out, and isn't that what the FBI is supposed to do?'"
