Quantum Control With Light Paves Way For Ultra-Fast Computers

control

Terahertz light can control some of the essential quantum properties of superconducting states, report researchers. Jigang Wang patiently explains his latest discovery in quantum control that could lead to superfast computing based on quantum mechanics: He mentions light-induced superconductivity without energy gap. He brings up forbidden supercurrent quantum beats. And he mentions terahertz-speed symmetry breaking. …

Testing Hyper-complex Quantum Theories With An Exotic Metamaterial

Hyper-complex Quantum Theories

Physicists have looked for deviations from standard quantum mechanics, testing whether quantum mechanics requires a more complex set of mathematical rules. A research team led by Philip Walther at the University of Vienna designed a photonic experiment using exotic metamaterials, which were fabricated at the University of California Berkeley. Their experiment supports standard quantum mechanics …

Time Scale Stretching For Improving Prediction Of Extreme Events

stretching time scales

A technique currently applied in the field of photonics could help predict rogue wave events on the ocean surface, along with other extreme natural phenomena. Stretching time scales to explore extreme events in nature is possible, according to a team from the Institut FEMTO-ST, which used an innovative measurement technique enabling the capture of such …

Diamond Nitrogen-vacancy Centers Power World’s Smallest Radio Receiver

nitrogen-vacancy centers

A tiny radio whose building blocks are the size of two atoms has been developed by Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences. Built out of an assembly of atomic-scale defects in pink diamonds, it is the world’s smallest radio receiver. The device can withstand extremely harsh environments and …

Meter-scale Optical Coherence Tomography Depth Barrier Broken

3d optical coherence tomography

The first ever optical coherence tomography (OCT) images of cubic meter volumes have been produced, through an industry-academic collaboration. The advance could open up many new uses for OCT in industry, manufacturing and medicine. It also marks a milestone toward developing a high-speed, low-cost optical coherence tomography system on a single integrated circuit chip. James …
