Photon purity is more than a technical detail. In photonic quantum computing, orderly single-photon streams are easier to ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University ...

A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. By measuring their interference at a beam-splitter through ...

New research has unveiled a new advancement in Light Detection and Ranging (LIDAR) technology, offering unparalleled sensitivity and precision in measuring the distance of remote objects. This ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

Quantum photonics is an interdisciplinary field that combines the principles of quantum mechanics and photonics to study and manipulate light at the single-photon level. It explores the generation, ...

Duality ellipse The amount of coherence is linked to the amount of waveness and particleness of a quantum system through an duality ellipse relation. The coherence, modulated by the object shape, can ...

For the first time, scientists have observed quantum interference—a wavelike interaction between particles related to the weird quantum phenomenon of entanglement—occurring between two different kinds ...

A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range ...
