Molecule-in-a-crystal system could boost quantum computing via chemically engineered qubits

Within a crystal’s atomic structure, tiny atomic-scale flaws will naturally occur where electrons can become trapped. These defects have emerged as one of the leading platforms for quantum information processing. Through a new study, posted to the preprint server arXiv, Ilai Schwartz and colleagues at NVision Imaging Technologies in Germany have shown that a specialized molecule embedded inside a crystal could take this approach a step further, offering a more controllable and versatile route to building quantum systems.

New eruption discovered in the Bismarck Sea

It’s a truism among oceanographers that there is more accurate mapping of the surface of the moon and Mars than of the deep-ocean floor. That’s especially true for the Bismarck Sea, a relatively deep body of water north of Papua New Guinea. It’s an ocean basin with a geologically complex seafloor rife with faults, volcanic features, rifts, scarps, and active subduction and spreading zones at depths that make high-resolution sonar mapping challenging.

Astronomers may have discovered the tiniest odd radio circle

Astronomers have identified a possible new member of one of astronomy’s strangest classes of objects: Odd radio circles (ORCs), enormous ring-like structures visible only at radio wavelengths. The newly discovered source, J1248+4826, appears to be the most compact ORC candidate identified so far, with a ring only about 30,000 parsecs across. The paper was posted to the arXiv preprint server on May 6.

Quantum sensors use atoms, electrons and light as ultra‑steady rulers

Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small that ordinary background noise can drown them out. Some sensors are already in daily use, while others are moving from research labs into flight tests, hospitals and field instruments.

Better helium reporting to improve fission and fusion materials modeling

Standardizing calculations of the helium byproducts generated in advanced fission and fusion energy system materials can increase reactor safety and longevity, according to a study led by University of Michigan Engineering with collaborators at Oak Ridge National Laboratory and its management contractor UT-Battelle.

Optoelectronic synapse shows exceptional photoresponse for neuromorphic vision

Like so much else in nature, the human visual system has both a complex structure and functional efficiency that is difficult for scientists to replicate. The system is both a sensor and a processor, with the eyes and the brain working together to resolve images with less energy use than anything people have invented.
