They say that one can miss the forest for the trees. But it’s often worth taking a closer look at the trees to make sense of the dense, brambly whole. That’s what a Stanford University group did to tackle a thorny quantum-information problem in diamond. A star material for hosting quantum information, diamond nevertheless presents … Read more
While atomic clocks are already the most precise timekeeping devices in the universe, physicists are working hard to improve their accuracy even further. One way is by leveraging spin-squeezed states in clock atoms. Spin-squeezed states are entangled states in which particles in the system conspire to cancel their intrinsic quantum noise. These states, therefore, offer … Read more
Quantum-based systems offer the promise of accelerated computing and fortified encryption, driving advancements in computation and communication. These systems rely on interconnected nodes within fiber networks, housing qubits and single-photon generators creating entangled photon pairs. Rare-earth (RE) atoms and ions within solid-state materials stand out as promising single-photon generators. Their compatibility with fiber networks and … Read more
A recent study conducted by researchers affiliated with the University of São Paulo (USP) in Brazil has shed light on the adverse effects of glitter particles on aquatic ecosystems. Glitter, which is composed of non-biodegradable microplastics, has been found to impede the growth of foundational organisms in these ecosystems, such as cyanobacteria, also known as … Read more
Halide perovskite light-emitting devices possess remarkable characteristics such as high efficiency, superior color purity, and an extensive color range. However, their integration into industrial applications is often hindered by the complex multilayer structure of the devices, as well as the stability issues caused by heating during operation. A promising solution to these challenges comes in … Read more
