Atoms queue up for quantum computer networks
In order to develop future quantum computer networks, it is necessary to hold a known number of atoms and read them without them disappearing. To do this, researchers from the Niels Bohr Institute have developed ...
New approach enhances quantum-based secure communication
University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets.
Yes, black holes exist in gravitational theories with unbounded speeds of propagation
Lorentz invariance (LI) is a cornerstone of modern physics, and strongly supported by observations.
Molten metal solidifies into a new kind of glass
(Phys.org) —When a molten material cools quickly, parts of it may have enough time to grow into orderly crystals. But if the cooling rate is too fast for the entire melt to crystallize, the remaining material ...
Distant quasar spectrum reveals no sign of changes in mass ratio of proton and electron over 12 billion years
In search for dark matter components, physicists edge closer by watching radiation shifts
(Phys.org) —Nuclear magnetic resonance—that phenomenon where nuclei of certain atoms, when in a magnetic field, take in and give off measurable amounts of electromagnetic radiation—is everywhere.
Researchers design first battery-powered invisibility cloak
Researchers at The University of Texas at Austin have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation.
A cure for clashing qubits: Researchers successfully entangle different-color photons
Swirls in remnants of big bang may hold clues to universe's infancy
South Pole Telescope scientists have detected for the first time a subtle distortion in the oldest light in the universe, which may help reveal secrets about the earliest moments in the universe's formation.
Researchers make magnetic graphene
Graphene, a one-atom thick sheet of carbon atoms arranged in a hexagonal lattice, has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic ...
Biology meets geometry: Describing geometry of common cellular structure
Architecture imitates life, at least when it comes to those spiral ramps in multistory parking garages. Stacked and connecting parallel levels, the ramps are replications of helical structures found in a ...
Quarks in six-packs: Exotic Particle Confirmed
For decades, physicists have searched in vain for exotic bound states comprising more than three quarks. Experiments performed at Jülich's accelerator COSY have now shown that, in fact, such complex particles ...
Physicists reach new milestone measuring half-life of iron-60
Fusion instabilities lessened by unexpected effect
(Phys.org) —A surprising effect created by a 19th century device called a Helmholz coil offers clues about how to achieve controlled nuclear fusion at Sandia National Laboratories' powerful Z machine.
