Nuclear spins in a crystal can be detected and manipulated through their interactions with the more accessible electron spin of a neighboring crystal defect. This strategy has enabled nanoscale magnetic resonance imaging and other quantum applications. But a long-standing challenge has been to target a specific nuclear spin, while protecting the delicate quantum nature of the electron spin. Important progress on this challenge has now been achieved by two teams at the Delft University of Technology in the Netherlands.

A study, led by the University of Portsmouth, has achieved unprecedented precision in detecting tiny shifts in light displacements at the nanoscale. This is relevant for example in the characterisation of birefringent materials and in high-precision measurements of rotations.

ICFO researchers, in an international collaboration, have used terahertz light to explore exotic phenomena within magic-angle twisted bilayer graphene. This approach reveals previously unseen behaviors and provides direct insights into the quantum geometry of electronic wavefunctions —the fundamental framework underlying these phenomena.

Led by D-Wave, an international collaboration including researchers from UBC’s Blusson QMI has achieved a major milestone in quantum annealing, pushing computing beyond classical limits to solve complex magnetic material simulation problems for materials discovery. The study was published in Science.

SkyWater Technology, Inc. (or “SkyWater”), a U.S.-based Trusted technology realization partner, and D-Wave Quantum, Inc. (or “D-Wave”), a leader in quantum computing systems, software and services, today announced that D-Wave’s Advantage2 annealing quantum computer prototype, fabricated by SkyWater, was used to achieve computational supremacy in quantum simulation. The landmark research was published today by the American Association for the Advancement of Science (AAAS), in its journal, Science, one of the world’s most respected scientific journals, known for publishing high-impact research that advances global scientific and technological progress.

Traditional black holes, as predicted by Albert Einstein’s theory of General Relativity, contain what are known as singularities, i.e. points where the laws of physics break down. Identifying how singularities are resolved in the context of quantum gravity is one of the fundamental problems in theoretical physics. Now, a team of experts from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) has described for the first time the creation of regular black holes from gravitational effects and without the need for the existence of exotic matter required by some previous models.

Researchers at the National Graphene Institute at the University of Manchester have achieved a significant milestone in the field of quantum electronics with their latest study on spin injection to graphene. The paper, published recently in Communications Materials, outlines ground-breaking advancements in spintronics and quantum transport.

Now, a team of researchers from IESL FORTH, Dr. Theocharis Lamprou and Dr. Paraskevas Tzallas, and ICFO, Dr. Javier Rivera-Dean, Philipp Stammer and ICREA Prof. Maciej Lewenstein, has successfully addressed both issues. They created generalized coherent state superpositions (GCSS), verified their quantum nature and employed them to drive a nonlinear optical process (which, per se, is indicative of the high photon number and intensity of the states). Their findings, demonstrated both theoretically and experimentally, have been reported in Physical Review Letters.

In meticulous research, Raman Research Institute (RRI) scientists analysed existing open-source data available on three of India's most sophisticated observatory sites, and found that the Indian Astronomical Observatory (IAO) in Hanle, nestled in the pristine heights of Ladakh, as the prime candidate for this revolutionary technology.

Researchers Deepak Singh and Carsten Ullrich from the University of Missouri’s College of Arts and Science, along with their teams of students and postdoctoral fellows, recently made a groundbreaking discovery on the nanoscale: a new type of quasiparticle found in all magnetic materials, no matter their strength or temperature.
