When a Quantum Computer Is Able to Break Our Encryption, It Won't Be a Secret

On 2023-09-13: There is already more than enough reason to upgrade our communications systems to resist attacks from quantum computers as soon as possible. Even if completely unexpected attacks from a black-swan quantum computer are unlikely, attacks from known or suspected quantum computers would already be plenty bad enough. - rand.org

Physicists Create New Magnetic Material to Unleash Quantum Computing

On 2023-09-18: Researchers from the University of Texas, El Paso have developed a highly magnetic quantum computing material that retains its magnetism at room temperature. The material, which does not contain high-demand rare earth minerals, exhibits superparamagnetic behavior, making it a potential option for creating qubits, the basic unit of quantum information. By synthesizing the material in a sequential process, the researchers were able to produce a material 100 times more magnetic than pure iron. Further testing is needed, but this development offers promising potential for stable qubits and advancements in quantum computing. - sciencealert.com
