A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

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

An international research team involving Paderborn University has achieved a crucial breakthrough on the road to a quantum internet. For the first time ever, the polarization state of a single photon ...

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

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

According to a Nature Communications report, the research was led by Jake Freedman and Matt Eichenfield, in collaboration ...

Controlled generation of single-photon emitters in silicon (red) by broad-beam implantation of ions (blue) through a lithographically defined mask (left) and by a scanned focused ion beam (right).

The process that powers much of life on Earth, photosynthesis, is so finely tuned that just one photon is enough to kick it off. Scientists have long suspected that photosynthesis must be sensitive to ...
