Scientists have managed for the first time to create a unidirectional device that significantly increases the quality of a special class of transmitted signals in optical communications: optical vortices. By transmitting selective optical vortex modes […]
Researchers have found an efficient way to identify ‘topological’ materials, whose surfaces can have different electrical or functional properties than their interiors. The approach should make it easier uncover materials that could be the basis […]
Computing power of quantum machines is currently still very low. Increasing it is still proving to be a major challenge. Physicists now present a new architecture for a universal quantum computer that overcomes such limitations […]
Scientists have created a Bose-Einstein condensate out of excitons — quasiparticles that combine electrons and positively charged ‘holes’ — in a semiconductor. Quasiparticle Bose-Einstein condensates have for six decades been something of a holy grail […]
Extreme miniaturization of infrared (IR) detectors is critical for their integration into next-generation consumer electronics, wearables and ultra-small satellites. Thus far, however, IR detectors have relied on bulky (and expensive) materials and technologies. A team […]
An improvement to a Nobel Prize-winning technology called a frequency comb enables it to measure light pulse arrival times with greater sensitivity than was previously possible — potentially improving measurements of distance along with applications […]
Researchers identified possible solutions to some of the limitations of qubits for quantum computing. They looked at two different hybrid quantum systems: an electron-superconducting circuit and an electron-ion coupled system. Both systems were able to […]
A team of scientists believe our brains could use quantum computation, after adapting an idea developed to prove the existence of quantum gravity to explore the human brain and its workings. The brain functions measured […]
Scientists have used ultrashort laser pulses to make the atoms of molecules vibrate and have gained a precise understanding of the dynamics of energy transfer that take place in the process. Click to rate this […]
A newly-discovered material structured like a honeycomb can transform from an electrical insulator, like rubber, into an electrical conductor, like metal, in a matter of seconds. Now, researchers think they can explain why. Click to […]
