Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how ...

Quantum entanglement links two particles, such as photons, so that measuring one instantly reveals information about the other. Reliable generation and distribution of entangled states are essential ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

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

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

A study from Technion unveils a newly discovered form of quantum entanglement in the total angular momentum of photons confined in nanoscale structures. This discovery could play a key role in 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 ...

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 ...

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 ...
