Biphoton state holographic reconstruction. Image reconstruction. a, Coincidence image of interference between a reference SPDC state and a state obtained by a pump beam with the shape of a Ying and Yang symbol (shown in the inset). The inset scale is the same as in the main plot. b, Reconstructed amplitude and phase structure of the image imprinted on the unknown pump. Credit: Nature Photonics (2023).

Credit: Unsplash/CC0 Public Domain It was a good year for research of all kinds as three men shared the Nobel Prize in physics for their work that showed that tiny particles separated from one another at great distances can be entangled. Alain Aspect, John Clauser and Anton Zeilinger won the award for their work showing that the counterintuitive field of quantum entanglement is real and also demonstrable.…
