Efficient and tunable interface for quantum networks

(Phys.org) -- Quantum computers may someday revolutionize the information world. But in order for quantum computers at distant locations to communicate with one another, they have to be linked together in a network. While ...

Atomic clock comparison via data highways

(Phys.org) -- Optical atomic clocks measure time with unprecedented accuracy. However, it is the ability to compare clocks with one another that makes them applicable for high-precision tests in fundamental theory, from cosmology ...

Physicists map spiraling light to harness untapped data capacity

Physicists with the Institute of Ultrafast Spectroscopy and Lasers (IUSL) at The City College of New York have presented a new way to map spiraling light that could help harness untapped data channels in optical fibers. Increased ...

Physicists break color barrier for sending, receiving photons

University of Oregon scientists have invented a method to change the color of single photons in a fiber optic cable. The laser-tweaked feat could be a quantum step forward for transferring and receiving high volumes of secured ...

US cities vie to win Google's broadband favor

A city in Kansas renamed itself "Google." A Florida mayor hopped into a tank full of sharks to impress the Internet titan. Baltimore named a "Google Czar" and scores of towns held "Google Days."

Carrier Pigeon Faster Than Broadband Internet

(PhysOrg.com) -- In South Africa, a carrier pigeon carrying a 4GB memory stick proved to be faster than the ADSL service from the country's biggest web firm, Telkom. Winston the pigeon took one hour and eight minutes to carry ...

NASA's new experimental antenna tracks deep space laser

An experimental antenna has received both radio frequency and near-infrared laser signals from NASA's Psyche spacecraft as it travels through deep space. This shows it's possible for the giant dish antennas of NASA's Deep ...
