Physics Nobel Prize poll: Quantum experiments and particle discoveries are the top picks
For the past month the Joint Quantum Institute (JQI) has sponsored a website allowing visitors to vote for the topic they believe will capture this year's Nobel Prize for physics. The site offered 14 Nobel-worthy ...
143 km: Physicists break quantum teleportation distance
Physicists at the University of Vienna and the Austrian Academy of Sciences have achieved quantum teleportation over a record distance of 143 km. The experiment is a major step towards satellite-based quantum ...
European team bests Chinese record at teleporting distance (Corrected)
Chinese group breaks distance record for teleporting qubits
'Quantum magic' without any 'spooky action at a distance'
The quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as "spooky action at a distance". A team of researchers led by Anton ...
Vienna physicists create quantum twin atoms
At the Vienna University of Technology, sophisticated atomchips have been used to create pairs of quantum mechanically connected atom-twins. Until now, similar experiments were only possible using photons.
Beam me up ... Quantum teleporter breakthrough
(PhysOrg.com) -- Researchers have achieved a breakthrough in quantum communications and computing using a teleporter and a paradoxical cat.
Time travel theory avoids grandfather paradox
A new ultrabright source of entangled photon pairs
At the very heart of applications such as quantum cryptography, computation and teleportation lies a fascinating phenomenon known as "entanglement". Two photons are entangled if the properties of one depend ...
