Quantum teleportation analysed by mathematical separation tool
Scientists from the University of Vienna's Faculty of Physics in Austria recently gave a theoretical description of teleportation phenomena in sub-atomic scale physical systems, in a publication in the European Physical Jo ...
Quantum correlations -- without entanglement
Quantum optical link sets new time records
Quantum communication could be an option for the absolutely secure transfer of data. The key component in quantum communication over long distances is the special phenomenon called entanglement between two ...
Large scale qubit generation for quantum computing
Hippie days: How a handful of countercultural scientists changed the course of physics in the 1970s
Every Friday afternoon for several years in the 1970s, a group of underemployed quantum physicists met at Lawrence Berkeley Laboratory, in Northern California, to talk about a subject so peculiar it was rarely ...
'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 ...
All-optical quantum computation, step 1: A controlled-NOT photonic gate
Matter-matter entanglement at a distance
(PhysOrg.com) -- Scientists at the Max Planck Institute of Quantum Optics prepare quantum mechanical entanglement of two remote quantum systems.
Simplifying the process of detecting genuine multiparticle entanglement
Apparent roadblock in the development of quantum lithography
14 quantum bits: Physicists go beyond the limits of what is currently possible in quantum computation
(PhysOrg.com) -- Quantum physicists from the University of Innsbruck (Austria) have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the ...
Entanglement can help in classical communication
A small quantum leap: New switching device could help build ultrafast quantum Internet
(PhysOrg.com) -- Northwestern University researchers have developed a new switching device that takes quantum communication to a new level. The device is a practical step toward creating a network that takes ...
