Since it was first demonstrated in the 1960s, spontaneous parametric down-conversion (SPDC) has been at the center of many quantum optics experiments that test the fundamental laws of physics in ...

A new method developed at the University of Bonn simplifies ultra-precise adjustment for quantum optics experiments. When individual atoms interact with each other, they often exhibit unusual behavior ...

Using artificial intellgence to find possibilities while humans gauge their significance is proving to be a powerful new form of scientific discovery. Back in 2009, computer scientists began ...

Is the cat in the box alive, dead or... alive-dead? Questions like the one posed by the Schroedinger's Cat thought experiment have vexed mere mortals for far too long, and the scientific community ...

An image from an experiment in the quantum optics laboratory in Cambridge. Laser light was used to excite individual tiny, artificially constructed atoms known as quantum dots, to create "squeezed" ...
