1+ day, 5+ hour ago   (536+ words) Scientists at Shanghai Jiao Tong University have unveiled a quantum neural operator that promises to squeeze genuine machine-learning power out of today’s noisy, error-prone quantum processors....

1+ day, 9+ hour ago   (709+ words) Quantum machine learning has long promised a new kind of computational power, but a quieter revolution is now underway at the intersection of quantum algorithms and data privacy....

1+ day, 9+ hour ago   (599+ words) Chemical bonds are usually treated as the fixed scaffolding of a material, the framework that determines how atoms sit relative to one another and how electrons move through the resulting structure. Yet in certain classes of matter, the bonds between…...

1+ day, 12+ hour ago   (581+ words) A quantum bit that has lost its coherence is usually written off as a casualty of its noisy environment, but a new theoretical study argues that this verdict is often premature — and, more importantly, predictable....

1+ day, 14+ hour ago   (625+ words) Silicon has long dominated the solar industry, but its fundamental physics imposes hard limits on how much sunlight a single-junction cell can convert into electricity. Photons with less energy than silicon’s band gap simply pass through the material, while photons…...

1+ day, 18+ hour ago   (70+ words) One of the most fundamental questions in quantum information theory is deceptively simple to state: given a quantum system that could be in any one of several possible states, how well can we guess which one it actually is? Because…...

1+ day, 20+ hour ago   (55+ words) Topological photonics has spent the past decade borrowing one of the most powerful ideas in modern condensed-matter physics: the notion that certain states of light can be protected from imperfections in much the same way that conducting edge states are…...

1+ day, 20+ hour ago   (92+ words) A team of quantum physicists in Morocco has revealed that the strange geometry underlying quantum states and the efficiency of quantum teleportation are far more intimately connected than previously appreciated. In a study published in Quantum Information Processing, Chaymae Boukacem,…...

1+ day, 21+ hour ago   (81+ words) Variational quantum algorithms have become the workhorses of near-term quantum computing, promising everything from molecular simulation to machine learning on hardware that is still noisy and small. Yet a stubborn bottleneck has shadowed the field from the start: training the…...

1+ day, 21+ hour ago   (668+ words) A long-predicted quirk of quantum materials has finally been caught in action. In an elegant set of experiments described in Nature Physics, researchers report the first demonstration of the Hall effect in a trion fluid, a charged three-particle state that…...
