Detecting dark matter, the invisible substance thought to keep galaxies intact, remains one of the most enduring mysteries in physics. Although it cannot be directly observed or touched, researchers suspect that dark matter leaves behind faint traces. These subtle signals might be detectable using advanced quantum technologies that can senseContinue Reading
Scientists from the RIKEN Center for Quantum Computing and Huazhong University of Science and Technology have carried out a theoretical study showing how a “topological quantum battery” could be efficiently designed. This innovative concept uses the topological characteristics of photonic waveguides and the quantum behavior of two-level atoms to storeContinue Reading
When arranged in just the right ways, two-dimensional materials can display unusual and valuable quantum effects such as superconductivity and exotic types of magnetism. Understanding why these effects arise, and how to control them, remains one of the biggest challenges for physicists and engineers. A new study published in NatureContinue Reading
Picture a future where factories can create materials and chemical compounds more quickly, at lower cost, and with fewer production steps. Imagine your laptop processing complex data in seconds or a supercomputer learning and adapting as efficiently as the human brain. These possibilities depend on one fundamental factor: how electronsContinue Reading
How likely you think something is to happen depends on what you already believe about the situation. This simple idea forms the basis of Bayes’ rule, a mathematical approach to calculating probabilities first introduced in 1763. Now, an international group of scientists has demonstrated how Bayes’ rule can also applyContinue Reading
Picture diving deep into the quantum realm, where unimaginably small particles can exist and interact in more than a trillion possible ways at the same time. It’s as complex as it sounds. To understand these mind-bending systems and their countless configurations, physicists usually turn to powerful supercomputers or artificial intelligenceContinue Reading
Quantum metals are metals where quantum effects — behaviors that normally only matter at atomic scales — become powerful enough to control the metal’s macroscopic electrical properties. Researchers in Japan have explained how electricity behaves in a special group of quantum metals called kagome metals. The study is the firstContinue Reading
Researchers at the Hebrew University of Jerusalem and the Humboldt University in Berlin have developed a way to capture nearly all the light emitted from tiny diamond defects known as color centers. By placing nanodiamonds into specially designed hybrid nanoantennas with extreme precision, the team achieved record photon collection atContinue Reading
Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics — or if it just looks like it does? In a groundbreaking study, physicists from Leiden, Beijing en Hangzhou found the answer to this question. You could call it aContinue Reading
UNSW Sydney nano-tech startup Diraq has shown its quantum chips aren’t just lab-perfect prototypes – they also hold up in real-world production, maintaining the 99% accuracy needed to make quantum computers viable. Diraq, a pioneer of silicon-based quantum computing, achieved this feat by teaming up with European nanoelectronics institute InteruniversityContinue Reading
