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 ...

Quantum entanglement among multiple indistinguishable particles typically manifests as either bright or dark states. Dark states are characterized by their near-total invisibility to emitted light, ...

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

Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to ...

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 ...

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 ...

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

Many quantum researchers are working toward building technologies that allow for the existence of a global quantum internet, in which any two users on Earth would be able to conduct large-scale ...
