1+ day, 4+ 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, 8+ 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, 8+ hour ago   (649+ words) Every quantum network ever proposed faces the same awkward problem: the superconducting circuits that store and process quantum information speak in microwaves, while the optical fibers that carry signals across cities and continents speak in light....

1+ day, 11+ 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, 12+ 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, 14+ hour ago   (795+ words) A team of cryptographers in China has unveiled the first publicly verifiable encryption scheme capable of withstanding the most aggressive class of attacks against encrypted cloud backups, a breakthrough that could reshape how organizations prove the integrity of duplicated data…...

1+ day, 17+ 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, 19+ 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, 19+ 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, 20+ 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…...
