Quantum ‘sealed envelope’ system enables ‘perfectly secure’ information storage

Contact: Adrian Kent apak@damtp.cam.ac.uk 44-122-376-0379 University of Cambridge A breakthrough in quantum cryptography demonstrates that information can be encrypted and then decrypted with complete security using the combined power of quantum theory and relativity – allowing the sender to dictate the unveiling of coded information without any possibility of intrusion or manipulation. Scientists sent encrypted…

Scientists prove Heisenberg’s intuition correct : Coded messages are disturbed by the Eavesdropper ;-)

Contact: Caron Lett caron.lett@york.ac.uk 44-019-043-22029 University of York An international team of scientists has provided proof of a key feature of quantum physics – Heisenberg’s error-disturbance relation – more than 80 years after it was first suggested. One of the basic concepts in the world of quantum mechanics is that it is impossible to observe…

Existence of new element confirmed

Contact: Dirk Rudolph Dirk.Rudolph@nuclear.lu.se 46-462-227-633 Lund University An international team of researchers, led by physicists from Lund University, have confirmed the existence of what is considered a new element with atomic number 115. The experiment was conducted at the GSI research facility in Germany. The results confirm earlier measurements performed by research groups in Russia.…

Researchers explore quantum entanglement: superluminal

Contact: Leanne Yohemas lmyohema@ucalgary.ca 402-220-7722 University of Calgary Paper in Physical Review Letters delves into phenomenon Einstein called ‘spooky’ Albert Einstein called quantum entanglement—two particles in different locations, even on other sides of the universe, influencing each other—”spooky action at a distance.” Einstein made the comment while criticizing quantum mechanics as incomplete—the phenomenon of quantum…

Tractor beam built from rings of laser light

  18:05 19 October 2012 by Jacob Aron Stand aside, Wesley Crusher: there’s a new tractor beam on deck that pulls objects using nothing more than laser light. The device has already grabbed NASA’s attention as it could one day prove useful on space missions. It is well known that light can push on objects…
