Team finds 'tipping point' between quantum and classical worlds

If we are ever to fully harness the power of light for use in optical devices, it is necessary to understand photons - the fundamental unit of light. Achieving such understanding, however, is easier said than done. That's ...

Quantum imaging: Pushing the boundaries of optics

Quantum mechanically entangled light particles break down the boundaries of conventional optics and allow a glimpse into previously invisible wavelength ranges, thus bringing about new possibilities for imaging techniques, ...

Exotic superconductors: The secret that wasn't there

A single measurement result is not a proof—this has been shown again and again in science. We can only really rely on a research result when it has been measured several times, preferably by different research teams, in ...

Generating multiphoton quantum states on silicon

In a recent study now published in Light: Science & Applications, Ming Zhang, Lan-Tian Feng and an interdisciplinary team of researchers at the departments of quantum information, quantum physics and modern optical instrumentation ...

Entangled LED first to operate in the telecom window

Researchers have demonstrated the first quantum light-emitting diode (LED) that emits single photons and entangled photon pairs with a wavelength of around 1550 nm, which lies within the standard telecommunications window. ...
