Scientists have shown that they can extend the life of a molecular qubit by changing the surrounding crystal structure to be less symmetric. The asymmetry protects the qubit from noise, enabling it to hold information five times longer than if it existed in a symmetric structure.

An international team of astronomers has conducted optical and near-infrared observations of a rare Icn-type supernova known as SN 2022ann. Study results posted November 9 on a preprint server arXivsheds more light … Read more
Artist’s conception of Cygnus A, surrounded by a ring of dust and debris with jets shooting out from its center. Magnetic fields trapping dust near the supermassive black hole at the galaxy’s core are illustrated. This initial study spurred a larger comparison of radio loudness with polarization and was included in the composite dataset. Credit: … Read more
A few hundred feet from where we are sitting there is a large metal chamber, airless and covered with wires needed to control the instruments within. A beam of particles passes through the chamber’s interior silently at about half the speed of light until it strikes a solid piece of matter, exploding rare isotopes. All … Read more
(a) Schematic of the hohlraum magnetized NIF generated from AuTa4 With solenoid coil to withstand the current. (b) X-ray drive measured with an LEH instrument and incident laser powers for magnetized and non-magnetized AuTa4 hohlraum and two non-magnetic hohlraums. “BF” stands for “BigFoot,” which was the name of the previous ignition design. attributed to him: … Read more
Polarization in a magnetic field perpendicular to wormholes with a different redshift coefficient α. Each color represents the observed polarization for orbitals at r = 6M (outer ring) and r = 4.5M (inner ring) for a given wormhole solution with α∈[0,3]. The polarization of the Schwarzschild black hole is given by a black dotted line … Read more
Ripples in space-time caused by the collision black holes She taught us a lot about these mysterious things. these gravitational waves Coding information about black holes: their masses, the shape of the inner spiral toward each other, their spins, and their orientations. From this, scientists made sure that most of the collisions We’ve seen between … Read more
Credit: CC0 Public Domain In the digital age and the advance towards quantum computing, protecting data from hacking attacks is one of the biggest challenges we face – and one that experts, governments and industries around the world are working hard to address. While this is an effort to build a more connected and secure … Read more
Artist’s illustration of a distant planet with a helium-rich atmosphere. A new study explains how and why these types of planets could be so common. Credit: NASA/JPL-Caltech For centuries, no one knew if we were alone in the universe – or if there were even other planets like ours. But thanks to new telescopes and … Read more
Supercomputers can beat us at chess and perform more calculations per second than the human brain. But there are other tasks our brains perform routinely that computers simply can’t match — interpreting events and situations and using imagination, creativity, and problem-solving skills. Our brains are amazingly powerful computers, using not just neurons but the connections … Read more
