What are the limits of quantum physics? This is a question that has been researched around the world for decades. If we want to make the properties of the quantum world technically usable, we need to understand whether objects that are significantly larger than atoms and molecules can also exhibit quantum phenomena.For example, small glass spheres with a diameter of one hundred nanometres can be examined – still over a thousand times smaller than a grain of sand, but huge by

These results hint at the possibility of paradigm-shifting optical quantum devices based not on conventional, difficult-to-scale components like waveguides and beam splitters, or even extended optical microchips, but instead on error-resistant metasurfaces that offer a host of advantages: designs that don’t require intricate alignments, robustness to perturbations, cost-effectiveness, simplicity of fabrication, and low optical loss. Broadly speaking, the work embodies metasur

Researchers have succeeded in unraveling for the first time the mystery of the 'electron tunneling' process, a core concept in quantum mechanics, and confirmed it through experiments. This study was published in the international journal Physical Review Letters and is attracting attention as a key to unlocking the long-standing mystery of 'electron tunneling,' which has remained unsolved for over 100 years.

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.

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.
