Spiral laser beam creates quantum whirlpool
(Phys.org) —Physicists at Australian National University have engineered a spiral laser beam and used it to create a whirlpool of hybrid light-matter particles called polaritons.
A piece of the quantum puzzle: High level of controllability needed to explore ideas in quantum simulations
While the Martinis Lab at UC Santa Barbara has been focusing on quantum computation, former postdoctoral fellow Pedram Roushan and several colleagues have been exploring qubits (quantum bits) for quantum ...
Shaking the topological cocktail of success
Graphene is the miracle material of the future. Consisting of a single layer of carbon atoms arranged in a honeycomb lattice, the material is extremely stable, flexible, highly conductive and of particular ...
Twisted light waves sent across Vienna
A group of researchers from Austria have sent twisted beams of light across the rooftops of Vienna.
The Peres conjecture is false: One of the most famous problems in quantum information physics solved
Since 1999, the conjecture by Asher Peres, who invented quantum teleportation, has piqued the interest of many scientists in the field. According to his hypothesis, the weakest form of quantum entanglement can never result ...
Queen's launches major celebration of the life and legacy of John Stewart Bell
Queen's University is today leading the celebrations of a landmark in modern science, made 50 years ago by John Stewart Bell, a Queen's University graduate and Nobel Prize for Physics nominee.
String field theory could be the foundation of quantum mechanics
Two USC researchers have proposed a link between string field theory and quantum mechanics that could open the door to using string field theory—or a broader version of it, called M-theory—as the basis ...
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 ...
Flying qubits make for a highly resilient quantum memory
Many Interacting Worlds theory: Scientists propose existence and interaction of parallel worlds
Griffith University academics are challenging the foundations of quantum science with a radical new theory based on the existence of, and interactions between, parallel universes.
Researchers control interplay of light and matter at the level of individual photons emitted by rubidium
Researchers led by Dr. Sebastian Slama of Tübingen University's Institute of Physics have succeeded in directing the fluorescence of ultracold atoms into surface plasmons – light waves oscillating across ...
Study demonstrates that quantum holograms could be a candidate for becoming quantum information memory
Biological membranes are mainly composed of lipid bilayers. Gaining a better understanding of adsorption of solution ions onto lipid membranes helps clarify functional processes in biological cells. Now, a new study provides ...
Physicists find simple solution for quantum technology challenge
A solution to one of the key challenges in the development of quantum technologies has been proposed by University of Sussex physicists.
When parallel worlds collide, quantum mechanics is born
Parallel universes – worlds where the dinosaur-killing asteroid never hit, or where Australia was colonised by the Portuguese – are a staple of science fiction. But are they real? ...
