The vast majority of modern quantum technologies—from quantum cryptography to the quantum internet to the quantum computer—rely on one essential element: the transmission of photons. Two qubits (two atoms, for example) exchange ...
Physicists at the University of Oxford have helped confirm that one of the strangest phenomena in physics—quantum entanglement—occurs even among some of the heaviest and most fleeting particles ever created. The discovery, ...
Astronomers have identified a peculiar radio transient in the Milky Way that has remained active for more than two decades, defying the behavior expected of known classes of galactic radio sources. The paper posted to the ...
Quantum computers promise to tackle problems that are extraordinarily difficult for today's computers. But there is a major obstacle: quantum systems are notoriously fragile. Noise, loss and even tiny disturbances can destroy ...
As our telescopes have improved and we've been able to peer farther back in time, we've begun finding more fascinating features of the universe. But one thing we haven't found for sure is Population III (Pop III) stars. These ...
Metallic nanostructures are exceptionally effective at concentrating light into tiny volumes, while dielectric nanostructures excel at storing light with minimal energy loss. Combining these complementary properties has traditionally ...
To monitor the amount and type of nuclear material at power plants and weapons facilities, scientists look for a special signal—the unique pattern of gamma rays emitted by specific radioactive elements. However, some of these ...
Within tiny halos of light clinging to a vanishingly thin wisp of optical fiber, scientist Jongmin Lee guides atoms like marbles through a narrow pipe. Rock the fiber and the atoms shift side by side; they just don't fall ...
Researchers have demonstrated that a naturally occurring mineral can serve as a low-loss optical material for next-generation broadband all–van der Waals nanophotonic components.
Light in the mid-infrared (mid-IR) portion of the electromagnetic spectrum plays a key role in modern sensing. Because molecules interact with this kind of light in specific ways, researchers use technologies like mid-IR ...
