The field of quantum physics is rife with paths leading to tantalizing new areas of study, but one rabbit hole offers a unique vantage point into a world where particles behave differently—through the proverbial looking glass.
Dubbed the"Alice ring" after Lewis Carroll's world-renowned stories on Alice's Adventures in Wonderland, the appearance of this object verifies a decades-old theory on how monopoles decay. Specifically, that they decay into a ring-like vortex, where any other monopoles passing through the center are flipped into their opposite magnetic charges.
Monopoles remain an elusive concept in the arena of quantum physics. As the name suggests, monopoles are the solitary counterpart of dipoles, which carry a positive charge at their north pole and a negative charge at the south. In contrast, a monopole carries only either a positive or negative charge.
"Think of the monopole as an egg teetering at the top of a hill," Möttönen said."The slightest perturbations can send it crashing down. In the same way, monopoles are subject to noise that triggers their decay into Alice rings."

Quantum computer unveils atomic dynamics of light-sensitive moleculesResearchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.

Chessboard-like method enables the operation of largest gate-defined quantum dot systemResearchers from Delft established a way to address many quantum dots with only a few control lines using a chessboard-like method. This enabled the operation of the largest gate-defined quantum dot system ever. Their result is an important step in the development of scalable quantum systems for practical quantum technology. They publish their results in Nature Nanotechnology.

Physicists develop series of quality control tests for quantum computersQuantum technologies—and quantum computers in particular—have the potential to shape the development of technology in the future. Scientists believe that quantum computers will help them solve problems that even the fastest supercomputers are unable to handle yet. Large international IT companies and countries like the United States and China have been making significant investments in the development of this technology. But because quantum computers are based on different laws of physics than conventional computers, laptops, and smartphones, they are more susceptible to malfunction.

First Quantum joins Rio in copper JVDiversified miner Rio Tinto has formed a joint venture (JV) with fellow major First Quantum over the development of the La Granja copper project, in Peru. Following the completion of conditions including regulatory approvals from the government of Peru, First Quantum has acquired a 55% stake in the project for $105-million. It will invest up to a further $546-million into the JV to sole fund capital and operational costs to take the project through a feasibility study and toward development.
