(PhysOrg.com) -- In the classical world, information can be copied and deleted at will. In the quantum world, however, the conservation of quantum information means that information cannot be created nor destroyed. This concept ...
(PhysOrg.com) -- Among the many intriguing concepts in Einstein’s relativity theories is the idea of closed timelike curves (CTCs), which are paths in spacetime that return to their starting points. As such, CTCs offer ...
(PhysOrg.com) -- In "ordinary" quantum entanglement, two particles possess properties that are inherently linked with each other, even though the particles may be spatially separated by a large distance. Now, physicists S. ...
(PhysOrg.com) -- Taking a step toward the realization of futuristic quantum technologies, a team of physicists from China and Germany has demonstrated a key element – an entangling gate – of a quantum teleportation ...
Researchers at the Computer Vision Lab at ETH Zurich, Switzerland, have developed a method with which they can produce virtual copies of real objects. The copies can be touched and even sent via the Internet. By incorporating ...
(PhysOrg.com) -- The possibility of going back in time only to kill your ancestors and prevent your own birth has posed a serious problem for potential time travelers, not even considering the technical details of building ...
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 on those of the ...
A team of European researchers has "virtually" teleported real objects through cyberspace, touched things in virtual reality and even felt the movements of a virtual dance partner.
(PhysOrg.com) -- Scientists in China have succeeded in teleporting information between photons further than ever before. They transported quantum information over a free space distance of 16 km (10 miles), much further than ...
(PhysOrg.com) -- University of Queensland physicists have demonstrated a novel solution to the problem of information degradation when amplifying signals at the quantum information level.
