Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

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

A new chip-based quantum memory uses 3D-printed “light cages” to store light in atomic vapor with high precision. Quantum ...

The technology’s applications span secure communications with multiple simultaneous channels, faster quantum computing ...

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

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 ...

Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a ...

Physicists from Imperial College London have achieved a groundbreaking milestone in quantum physics by reimagining the ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...
