For now, full-fledged quantum computers are the stuff of science fiction — in last summer’s blockbuster movie Transformers, the bad guys use quantum computing to break into the U.S. Army's secure files in just 10 seconds ...
Scientists at the California Institute of Technology have laid the groundwork for a crucial step in quantum information science. They show how entanglement, an essential property of quantum mechanics, can be generated between ...
In an important step for the infant field of quantum communications, researchers from the University of Geneva in Switzerland have, for the first time, realized an “entanglement swapping” experiment with photon pairs ...
Error correction coding is a fundamental process that underlies all of information science, but the task of adapting classical codes to quantum computing has long bumped up against what seemed to be a fundamental limitation.
As if plain old quantum entanglement weren’t strange enough for modern physics, now physicists are entangling already entangled particles. In entanglement swapping, one particle of an entangled pair becomes entangled with ...
Like virtuosos tuning their violins, researchers at the University of Illinois at Urbana-Champaign have tuned their instruments and harmonized the production of entangled photons, pushing rates to more than 1 million pairs ...
(Phys.org)—The pursuit of an understanding of the base machinery of the mind led early researchers to anatomical exhaustion. With neuroscience now in the throes of molecular mayhem and a waning biochemical bliss, physics ...
Even though quantum computers are a young technology and aren't yet ready for routine practical use, researchers have already been investigating the theoretical constraints that will bound quantum technologies. One of the ...
Some powerful rulers of the world may dream of the possibility to get in touch with their colleagues on different continents unnoticed by friends or foes. Someday, new quantum technologies could allow for making these wishes ...
Our intuition tells us that it should be impossible to see whether two identical objects have been swapped back and forth, and for all particles observed to date, that has been the case. Until now.
