Physicists at the Institute of Science and Technology Austria (IST Austria) have invented a new radar prototype that utilizes quantum entanglement as a method of object detection. This successful integration of quantum mechanics into our everyday devices could significantly impact the biomedical and security industries. The research is published in the journal Science Advances.

Quantum entanglement is a physical phenomenon where two particles remain inter-connected, sharing physical traits regardless of how far apart they are from one another...

Future Information Technologies 3D Quantum Spin Liquid Revealed

One of the four magnetic interactions leads to a three-dimensional network of corner-sharing triangles also known as the hyperkagome lattice. Combined the magnetic interactions form a hyper-hyper-Kagome lattice which allows the 3D quantum spin liquid behavior.

Quantum spin liquids are candidates for potential use in future information technologies. So far, quantum spin liquids have usually only been found in one or two dimensional magnetic systems only. Now an international team has investigated crystals of PbCuTe2O6 with neutron experiments.

They found spin liquid behaviour in 3D, due to a so called hyper hyperkagome lattice. The experimental data fit extremely well to theoretical simulations also done at HZB.

IT devices today are based on electronic processes in semi...

Computers, mobile phones and all other electronic devices contain thousands of transistors, linked together by thin films of metal. Scientists at Linköping University, Sweden, have developed a method that can use the electrons in a plasma to produce these films.

The processors used in today’s computers and phones consist of billions of tiny transistors connected by thin metallic films. Scientists at Linköping University, LiU, have now shown that it is possible to create thin films of metals by allowing the free electrons in a plasma take an active role...

Shedding New Light on Nanolasers using 2D Semiconductors

The process Cun-Zheng Ning and his team used to create nanolasers with 2D semiconductor materials.
In research conducted by Cun-Zheng Ning and his ASU and Tsinghua University collaborators, a single layer of 2D material was placed on a carefully designed substrate with gold as a back-gate to control the number of electrons in the material. Another laser pumps the 2D material to create excitons, some of which form trions with the pre-existing electrons. The reflected light is monitored to find the signature of amplification.

Scientists have discovered a process of physics that enables low-power nanolasers to be produced in 2D semiconductor materials. Understanding the physics behind lasers at nanoscale and how they interact with semiconductors can have major implications for high-speed communication channels for supercomputers and data centers.
