The breakthrough is the first-ever transfer, or teleportation, of a particular complex set of quantum information from one point to another, opening the way for high-speed, high-fidelity transmission of large volumes of information, such as quantum encryption keys, via quantum communications networks.

Quantum technology derives its potential by exploiting uniquely quantum features such as superposition and entanglement. Single photons are excellent quantum information carriers, because they are naturally almost perfectly isolated from their environment. Also, quantum computers based on photons promise to be extremely fast.

"My goal is to make quantum communication devices very practical," said Prem Kumar, AT&T Professor of Information Technology in the McCormick School of Engineering and Applied Science and senior author of the paper. "We work in fiber optics so that as quantum communication matures it can easily be integrated into the existing telecommunication infrastructure."

This surprising discovery brings scientists one step closer to designing and building real-life quantum computing systems - devices that could have enormous potential across a wide range of fields, from drug design, electronics, and even code-breaking.

"Fifty years ago today, on December 29, 2009, Richard P. Feynman gave an after-dinner talk in Pasadena at an annual post-Christmas meeting of the American Physical Society. Here is how Ed Regis describes the setting of the lecture in his rollicking book Nano: In the banquet room [at the Huntington-Sheraton hotel in Pasadena], a giddy mood prevails. Feynman, although not yet the celebrity physicist he'd soon become, was already famous among his peers not only for having coinvented quantum electrodynamics, for which he'd later share the Nobel Prize, but also for his ribald wit, his clownishness, and his practical jokes. He was a regular good-time guy, and his announced topic for tonight was "There's Plenty of Room at the Bottom" - whatever that meant. "He had the world of young physicists absolutely terrorized because nobody knew what that title meant," said physicist Donald Glaser. "Feynman didn't tell anybody and refused to discuss it, but the young physicists looked at the title 'There's Plenty of Room at the Bottom' and they th"

"When we manage to make devices well on the nanoscale, we can then move on to make much smaller and finer structures that will go beyond conventional transistors to open up the possibility for more sophisticated devices that use electrons more like light than particles," he said. "If we can factor quantum mechanical features into electronics, that is going to open up a lot of new possibilities."

"This work represents a quantum jump forward in the complexity and function of circuits built from the bottom up, and thus demonstrates that this bottom-up paradigm, which is distinct from the way commercial circuits are built today, can yield nanoprocessors and other integrated systems of the future,"

Such potentially highly efficient cells, coupled with their low cost per unit area, are called Third (or Next) Generation Solar Cells.

"However, our results show that if the graphite layer is curved into a tube with a diameter of just a few nanometers, the spin of the individual electrons are suddenly strongly influenced by the motion of the electrons. When the electrons on the nanotube are further forced to move in simple circles around the tube the result is that all the spins turn in along the direction of the tube", explain the researchers Thomas Sand Jespersen and Kasper Grove-Rasmussen at the Nano-Science Center at the Niels Bohr Institute.
