Pure quantum state without the need for cooling
Three nano glass spheres cling to one another. They form a tower-like cluster, similar to when you pile three scoops of ice cream on top of one another – only much smaller. The diameter of the nano cluster is ten times smaller than that of a human hair. With the help of an optical device and laser beams, researchers at ETH Zurich have succeeded in keeping such objects almost completely motionless in levitation. This is significant when it comes to the future development of qu


Ripples of the future: Rice researchers unlock powerful form of quantum interference
The research team studied how phonons interfere with each other by looking at the shape of their signal in Raman spectroscopy, a technique that measures the vibrational modes of a material. The spectrum revealed a sharply asymmetric line shape and in some cases showed a complete dip, forming an antiresonance pattern characteristic of intense interference. The effect proved highly sensitive to the specificities of the silicon carbide surface. The comparison between three diffe


Quantum freezing at room temperature
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


Could metasurfaces be the next quantum information processors?
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


Unveiling the mystery of electron dynamics in the 'quantum tunneling barrier' for the first time
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.


New quantum record: Transmon qubit coherence reaches millisecond threshold
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.


A 1960s idea inspires NBI researchers to study hitherto inaccessible quantum states
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.


Atomic X-ray laser opens door to attosecond imaging
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.


Advent of the topological quantum battery
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.


Oxford physicists recreate extreme quantum vacuum effects
Using advanced computational modelling, a research team led by the University of Oxford has achieved the first-ever real-time, three-dimensional simulations of how intense laser beams alter the ‘quantum vacuum’—a state once assumed to be empty, but which quantum physics predicts is full of virtual electron-positron pairs.


Controlling quantum motion and hyper-entanglement
In hyper-entanglement, two characteristics of a particle pair are correlated. As a simple analogy, this would be like a set of twins separated at birth having both the same names and same types of cars: The two traits are correlated between the twins. In the new study, Endres and his team were able to hyper-entangle pairs of atoms such that their individual states of motion and their individual electronic states—their internal energy levels—were correlated among the atoms.


New quantum phase realised in a cold-atom quantum simulator
The work is set to open new avenues for the study of the exotic physics arising from the interplay of interactions and a magnetic field. This includes, for example, microscopic studies of the fractional quantum Hall effect and its properties such as anyonic excitations, long-range entanglement and topological order. These phenomena offer the potential to deepen our understanding of fundamental quantum physics while also paving the way for practical applications, for example i
