Using a superconducting circuit, they demonstrated a method to bypass an intermediate energy state without directly interacting with it—an advancement that could lead to more powerful and efficient quantum computing.

A groundbreaking data storage technology could preserve an entire human genome in a tiny 5D memory crystal. Developed by researchers at the University of Southampton, this innovation has the potential to last billions of years, offering an unprecedented solution for long-term data preservation.
Beyond human genetics, the technology could safeguard the genomes of endangered species. If future science enables species revival, these stored genetic blueprints might help restore lost biodiversity. The crystals could also serve as an indestructible archive of human knowledge.
Unlike conventional storage methods —hard drives, magnetic tapes, or optical discs—the 5D crystal doesn’t degrade over time. Standard formats fail within decades, but this breakthrough resists extreme conditions without data loss. It could endure for billions of years, even in the harshest environments.
Additionally, their ability to penetrate various materials without harmful radiation makes them valuable for security screening, quality control in industries, and chemical sensing. However, until now, it has been challenging to harness the potential of these waves in electronic devices due to several technological limitations.
Finally, a new study from researchers at MIT reveals a chip-based solution that can overcome these limitations and make terahertz waves more accessible than ever.
Terahertz (THz) waves are affected by the dielectric constant, a measure of how well a material can store and slow down an electric field. The lower this constant is the smoother terahertz waves can pass through a material.

Rubidium could be the next key player in oxide-ion conductors. Researchers at the Institute of Science Tokyo have discovered a rare rubidium (Rb)-containing oxide-ion conductor, Rb5BiMo4O16, with exceptionally high conductivity.
Identified through computational screening and experiments, its superior performance stems from low activation energy and structural features like large free volume and tetrahedral motion. Its stability under various conditions offers a promising direction for solid oxide fuel cells and clean energy technologies.
Oxide-ion conductors enable oxide ions (O2-) to be transported in solid oxide fuel cells (SOFCs), which can run on diverse fuels beyond hydrogen, including natural gas, and biogas, and even certain liquid hydrocarbons. This flexibility makes them particularly valuable during the transition to a hydrogen economy.
Scientists have now mapped the forces acting inside a proton, showing in unprecedented detail how quarks—the tiny particles within—respond when hit by high-energy photons.
The international team includes experts from the University of Adelaide who are exploring the structure of sub-atomic matter to try and provide further insight into the forces that underpin the natural world.
“We have used a powerful computational technique called lattice quantum chromodynamics to map the forces acting inside a proton,” said Associate Professor Ross Young, Associate Head of Learning and Teaching, School of Physics, Chemistry and Earth Sciences, who is part of the team.
A breakthrough in quantum computing that could threaten crypto is still years away, but a new chip from Microsoft might have shortened that timeline, says Bitcoin platform River.

Quantum computing will never be the same again. Join host Konstantinos Karagiannis for a special onsite interview at Microsoft Azure Quantum labs, where he was invited to see the launch of Majorana 1, the world’s first quantum processor powered by topological qubits. On the day this episode is posted, Nature will release a paper validating how Microsoft was able to create a topoconductor, or new material stack of indium arsenide and aluminum, built literally one atom at a time, to bring quantum particles called Majoranas into usable form. The resulting topological qubits have a unique shape called a tetron and can be accurately measured with lower errors than other modalities. Starting with a 4×2 grid of qubits, this same tiny device will hold 1 million qubits in a few years because of its unique system of wiring and measurement. This interview with Chetan Nayak from Microsoft happened a few feet away from a working Majorana 1 system.
