Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

While usual gapless points that are not geometrically defective i.e. Dirac points (Left column) possess only eigenvalues within [0, 1] (Bottom Left), defective exceptional points (Right column) also ...

The emergence of quantum entanglement is one of the fastest processes in nature. Scientists show that using special tricks, this can be investigated on an attosecond scale. Scientists have managed to ...

Quantum computers are able to solve complex calculations that would take traditional computers thousands of years in just a few minutes. What if that analytical power is turned inwards towards the ...

The simplified formula was developed to analyze local quantum entanglement in nanoscale materials. News organizations may use or redistribute this image, with proper attribution, as part of news ...

Here’s what you’ll learn when you read this story: Creating quantum entanglement from scratch can be tricky business, so researchers are exploring ways that entangled pairs can “share” these states ...

A further benefit is that the channels can be multiplexed, allowing many quantum processors to access the system at the same ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Tiny 3D-printed “light cages” are giving researchers a new way to catch and hold individual particles of light on a chip, a ...
