Stevens Institute, Hoboken, reports the universal identity P²+K²=1, uniting polarization with entanglement across setups and ...

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

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

A team of researchers at the University of Waterloo have made a breakthrough in quantum computing that elegantly bypasses the ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

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

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.

Photonic says it’s trying to build the world’s first highly scalable fault-tolerant quantum computer. It’s doing so with a ...

Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...
