darpaDARPA wants control of Light and Matter Interactions

0
A unique class of engineered light-manipulating materials, known as metamaterials or structured materials, makes use of patterns of strongly interacting wavelength or sub-wavelength-sized elements. Because of these intricate internal and surface structures, new properties have emerged, some exhibiting behavior that …

0
Nextbigfuture was able to ask Rob Hoyt of Tethers Unlimited how he will be able to use 27 large high low-earth orbit satellites to provide high-speed internet directly to smartphones. The GlobalFi approach will be to put all of the …

darpaDARPA funds developing Quantized Inertia into breakthrough space propulsion

0
DARPA is giving $1.3 million for a four-year study of quantized inertia (QI) for possible breakthrough space propulsion. The QI theory predicts that objects can be pushed by differences in the intensity of so-called Unruh radiation in space, similar to …

lasersProgress to photonic quantum computation

0
One of the goals of photonics is to implement photonic quantum computation. Quantum interference of single photons at a 50:50 beamsplitter is a key phenomenon in quantum physics and lies at the heart of linear optical quantum computation. Researchers have …

0
Korean Fusion tokamak fusion reactor scientists have determined additional magnetic field can avoid a difficult plasma instability. Nature – 3D field phase-space control in tokamak plasmas Abstract A small relaxation of the axisymmetric magnetic field of a tokamak into a …

nanowireSuperconducting nanowires created that are promising for future quantum computers

0
Dutch researchers have successfully developed nanowires allowing individual electrons to be captured by a ‘quantum dot’ on which superconductivity can take place. These nanowires could make powerful quantum computers. The combination of a quantum dot and superconductivity makes it possible …

mathematicsPatterns found in Prime Numbers

0
A new analysis by Princeton University researchers has uncovered patterns in primes that are similar to those found in the positions of atoms inside certain crystal-like materials. The discovery may aid research in both mathematics and materials science. “Prime numbers …

Two groups report technical breakthroughs for trapped neutral atom quantum computers. Optical engineering for sorting atoms into 3D patterns Barredo and team report their use of precision optical-engineering methods to sort atoms into arbitrary 3D patterns. Barredo et al. extend …

energy100 times larger nanoscale heat flow will lead to controlled heat flow in buildings and electronics

0
100 times more heat than predicted by the standard radiation theory can flow between two nanoscale objects, even at bigger-than-nanoscale distances. Applications of this could be better solar cells, materials that behave like one-way valves for heat flow and heat-based …
