One of the key requirements of future optical communications technologies is a nanoscale light source capable of emitting ultrafast light pulses. In a new study, researchers have shown that graphene may be an ideal candidate ...

Physicists have designed a new method for transmitting big quantum data across long distances that requires far fewer resources than previous methods, bringing the implementation of long-distance big quantum data transmission ...

In 1993, physicist Lucien Hardy proposed an experiment showing that there is a small probability (around 6-9%) of observing a particle and its antiparticle interacting with each other without annihilating—something that is ...

Light, which travels at a speed of 300,000 km/sec in a vacuum, can be slowed down and even stopped completely by methods that involve trapping the light inside crystals or ultracold clouds of atoms. Now in a new study, researchers ...

When trying to understand the origins of life on Earth, researchers run into a paradox: while water is an indispensable solvent for all known life forms that exist today, water also inhibits the formation of string-like chains ...

Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. The different colors are emitted from different parts of the quantum dot—red from the core, green from ...

Physicists have experimentally demonstrated an information engine—a device that converts information into work—with an efficiency that exceeds the conventional second law of thermodynamics. Instead, the engine's efficiency ...

Ever since cuprate (copper-containing) superconductors were first discovered in 1986, they have greatly puzzled researchers. Cuprate superconductors have critical superconducting temperatures—the point at which their electrical ...

According to the World Bank, corruption scandals siphon more than $2 trillion per year from the global economy, making corruption one of the major causes of slow economic growth and socioeconomic inequality. Now in a new ...

By shining a laser along the inside shell of an incandescent light bulb, physicists have performed the first experimental demonstration of an accelerating light beam in curved space. Rather than moving along a geodesic trajectory ...

Searching large, unordered databases for a desired item is a time-consuming task for classical computers, but quantum computers are expected to perform these searches much more quickly. Previous research has shown that Grover's ...

For the first time, researchers have experimentally observed light emission from individual graphene nanoribbons. They demonstrated that 7-atom-wide nanoribbons emit light at a high intensity that is comparable to bright ...

For the first time, physicists have developed a method to visually image the entanglement between electrons. As these correlations play a prominent role in determining a molecule's wave function—which describes the molecule's ...

By designing a solid electrolyte that is rigid on one side and soft on the other, researchers have fabricated a lithium-metal battery that completely suppresses dendrite formation—a major safety hazard that can cause fires ...

As a hard and brittle material, silicon has practically no natural elasticity. But in a new study, researchers have demonstrated that amorphous silicon can be grown into superelastic horseshoe-shaped nanowires that can undergo ...
