The rate at which quantum computing is hitting the media stream is ever-increasing. This piece is a collection of recent articles and reports covering various aspects of quantum computing from the lens of science and research. Mea Cubitt
Quantum material stretches to boost superconductivity | In a surprising discovery, an international team of researchers, led by scientists at the University of Minnesota, found that deformations in a quantum material can cause imperfections in its crystal structure that can actually improve the material’s superconducting and electrical properties.

Exotic magnetic states in miniature dimensions | Led by scientists at Empa and the International Iberian Nanotechnology Laboratory, an international team of researchers from Switzerland, Portugal, Germany, and Spain have succeeded in building carbon-based quantum spin chains, where they captured the emergence of one of the cornerstone models of quantum magnetism first proposed by the 2016 Nobel laureate F. D. M. Haldane in 1983. Source: nanowerk. Exotic magnetic states in miniature dimensions…
Atoms and molecules make vortex beams | A wave-like property previously only seen in beams of light and electrons has been observed for the first time in atoms and molecules. By passing beams of helium and neon through a grid of specially shaped nanoslits, researchers led by Edvardas Narevicius of Israel’s Weizmann Institute of Science succeeded in giving the beams a non-zero orbital angular momentum (OAM). The resulting structures are known vortex beams, and they could be used for fundamental physics studies such as probing the internal structure of protons. Source: physicsworld.

Research Team Unlocks Secret Path to a Bright Quantum Future | In 1998, researchers including Mark Kubinec of UC Berkeley performed one of the first simple quantum computations using individual molecules. They used pulses of radio waves to flip the spins of two nuclei in a molecule, with each spin’s “up” or “down” orientation storing information in the way that a “0” or “1” state stores information in a classical data bit. In those early days of quantum computers, the combined orientation of the two nuclei – that is, the molecule’s quantum state – could only be preserved for brief periods in specially tuned environments. In other words, the system quickly lost its coherence. Control over quantum coherence is the missing step to building scalable quantum computers. Source: SciTechDaily.

Experiments reveal formation of a new state of matter: Electron quadruplets | The central principle of superconductivity is that electrons form pairs. But can they also condense into foursomes? Recent findings have suggested they can, and a physicist at KTH Royal Institute of Technology today published the first experimental evidence of this quadrupling effect and the mechanism by which this state of matter occurs.
