Researchers invent method to ‘sketch’ quantum devices with focused electrons

It has long been a dream to invent new materials from the “top down” choosing which atoms go where to engineer properties of interest. A technique created by researchers out of the Department of Physics and Astronomy enables them to “sketch” patterns of electrons into a programmable quantum material—lanthanum aluminate/strontium titanate or “LAO/STO”. Using this approach, they can create quantum devices…

Fujifilm and IBM Set World Record With 580TB Magnetic Tapes

An anonymous reader quotes a report from PCMag.com: Mark Lantz, Manager of Advanced Tape Technologies at IBM Research, explains how researchers at IBM and Fujifilm brought together more than 15 years of work to set a new world record in tape storage. What they achieved is an areal density of 317Gbpsi (gigabits per square inch), which translates to a single tape…

Scientists expand space instrument’s capabilities

A new study by Southwest Research Institute scientists describes how they have expanded the capabilities of the prototype spaceflight instrument Chemistry Organic and Dating Experiment (CODEX), designed for field-based dating of extraterrestrial materials. CODEX now uses two different dating approaches based on rubidium-strontium and lead-lead geochronology methods. The instrument uses laser ablation resonance ionization mass spectrometry (LARIMS) to obtain dates using…

EU Sanctions Russia Over 2015 German Parliament Hack

The European Union has imposed sanctions today against Russia for its involvement in the 2015 German Parliament (Bundestag) hack. From a report: Sanctions were levied against the GRU (Russian Main Intelligence Directorate), a military intelligence agency part of the Russian Army, and two of its officers. The two GRU officers were identified as Dmitry Badin and Igor Kostyukov. EU officials said…

400 TB Storage Drives In Our Future: Fujifilm

One of the two leading manufacturers of tape cartridge storage, FujiFilm, claims that they have a technology roadmap through to 2030 which builds on the current magnetic tape paradigm to enable 400 TB per tape. AnandTech reports: As reported by Chris Mellor of Blocks and Files, Fujifilm points to using Strontium Ferrite grains in order to enable an areal data density…

Arrays of strontium Rydberg atoms show promise for use in quantum computers

A team of researchers at California Institute of Technology has found that arrays of strontium Rydberg atoms show promise for use in a quantum computer. In their paper published in the journal Nature Physics, the researchers describe their study of quantum entangled alkaline-earth Rydberg atoms arranged in arrays and what they learned about them. In the same issue, Wenhui Li, with…

What is a globular cluster?

Globular clusters are spherical collections of up to perhaps a million stars, orbiting mostly in the star halo of spiral galaxies, containing some of a galaxy’s oldest stars. Source: https://earthsky.org/space/definition-what-is-a-globular-cluster…

Qubits made from strontium and calcium ions can be precisely controlled by technology that already exists

Of the many divergent approaches to building a practical quantum computer, one of the most promising paths leads toward ion traps. In these traps, single ions are held still and serve as the basic units of data, or qubits, of the computer. With the help of lasers, these qubits interact with each other to perform logic operations. …

Simulation of dwarf galaxy reveals different routes for strontium enrichment

Simulations of a dwarf galaxy by RIKEN astrophysicists have revealed the various processes by which moderately heavy metals such as strontium are birthed. They have found that at least four kinds of stars are needed to explain the observed abundance of these metals in dwarf galaxies.
