Quantum memory for communication networks of the future

  • PDF
TechAndComputer (Nov. 15, 2010) — Researchers from the Niels Bohr Institute at the University of Copenhagen have succeeded in storing quantum information using two 'entangled' light beams. Quantum memory or information storage is a necessary element of future quantum communication networks. The new findings are published in Nature Physics.

Quantum networks will be able to protect the security of information better than the current conventional...

Long distance, top secret messages: Critical component of quantum communication device may enable cryptography

  • PDF
TechAndComputer (Oct. 20, 2010) — When the military needs to send the key to encrypted data across the world, it can't necessarily rely on today's communication lines, where the message could be covertly intercepted. But physicists at the Georgia Institute of Technology in Atlanta are developing a new, more secure way to send such information across far distances, using existing cables and the laws of quantum mechanics.

New malware could steal users social media behavior and info, researchers warn

  • PDF
TechAndComputer (Oct. 14, 2010) — A new study by Ben-Gurion University of the Negev (BGU) researchers predicts that a new generation of malware (software written for malicious purposes like identity theft) could steal data on human behavior patterns, which is more dangerous than traditional, detectable attacks.

In the newly published paper, "Stealing Reality," Dr. Yaniv Altshuler and Dr. Yuval Elovici from BGU discuss malware threats that extract...
