An international team of researchers from Leibniz University Hannover (Germany), the University of Twente (Netherlands), and the start-up company QuiX Quantum has presented an entangled quantum light source fully integrated for the first time on a chip. The results of the study were published in the journal Nature Photonics.

“Our breakthrough allowed us to shrink the source size by a factor of more than 1,000, allowing reproducibility, stability over a longer time, scaling, and potentially mass-production. All these characteristics are required for real-world applications such as quantum processors,” says Prof. Dr...

Breakthrough could point the way towards new quantum technology. University of Chicago physicists have invented a “quantum flute” that, like the Pied Piper, can coerce particles of light to move together in a way that’s never been seen before.

Described in two studies published in Physical Review Letters and Nature Physics, the breakthrough could point the way towards realizing quantum memories or new forms of error correction in quantum computers, and observing quantum phenomena that cannot be seen in n...

Physicists at LMU, together with colleagues at Saarland University, have successfully demonstrated the transport of an entangled state between an atom and a photon via an optic fiber over a distance of up to 20 km – thus setting a new record.

‘Entanglement’ describes a very particular type of quantum state which is not attributed to a single particle alone, but which is shared between two different particles. It irrevocably links their subsequent fates together – no matter how far apart they are – which famously led Albert Einstein to call the phenomenon as “spooky action at a distance”...

New laser uses light to create sound. A team of international researchers led by engineers at Washington University in St. Louis has seen the light and now has a lasing system that produces “good vibrations.” They developed a lasing system already adept at producing tiny light packets called photons into a tunable system that also makes little bits of mechanical energy called phonons – the energy products of oscillation, or vibration...
