On July 8, 2025, physicists from Aalto University in Finland published a transmon qubit coherence dramatically surpassing previous scientifically published records. The millisecond coherence measurement marks a quantum leap in computational technology, with the previous maximum echo coherence measurements approaching 0.6 milliseconds.

In a growing and very competitive research landscape in quantum, this work demonstrates the versatility of the semiconductor–superconductor platform to realize and study new types of quantum states.

Researchers at the International Iberian Nanotechnology Laboratory (INL) in Braga, Portugal, have achieved a major breakthrough at the intersection of quantum materials and nanotechnology.

Scientists have developed a new X-ray laser approach that generates the shortest pulses of high-energy X-rays to date, clocking in at 60-100 attoseconds (quintillionths of a second). By using a powerful laser to stimulate inner shell electrons—those closest to an atomic nucleus—this fast and powerful technique captures detailed movements of electrons, enabling the study of quantum-scale phenomena previously thought unobservable.

Engineers have harnessed quantum physics to detect the presence of biomolecules without the need for an external light source, overcoming a significant obstacle to the use of optical biosensors in healthcare and environmental monitoring settings.

Researchers from the RIKEN Center for Quantum Computing and Huazhong University of Science and Technology have conducted a theoretical analysis demonstrating how a “topological quantum battery”—an innovative device that leverages the topological properties of photonic waveguides and quantum effects of two-level atoms—could be efficiently designed.
