'Space-time cloak' to conceal events revealed in new study

(PhysOrg.com) -- The study, by researchers from Imperial College London, involves a new class of materials called metamaterials, which can be artificially engineered to distort light or sound waves. With conventional materials, ...

'Spooky action at a distance' aboard the ISS

(Phys.org) —Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively small distances ...

Two photons strongly coupled by glass fiber

Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and very intense light. Scientists in Vienna have now created the strongest ...

Scientists demonstrate all-fiber quantum logic

A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the controlled-NOT quantum logic gate in optical fibres with high fidelity.
