In 2024, a quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber ...

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 ...

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

Quantum communication has long promised unbreakable encryption, but the hardware has struggled to escape the lab. A new generation of laser-written glass chips is changing that equation, carving three ...

The consortium of the BMBF project SPINNING coordinated by Fraunhofer IAF has succeeded in decisively advancing the development of spin-photon-based quantum computers. On October 22 and 23, 2024, the ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

Quantum physics may sound abstract, but Ph.D. candidates Kirsten Kanneworff and David Dechant show that quantum research can also be very concrete. Together, they are investigating how quantum ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist ...

Research reveals how close human vision comes to sensing the smallest possible unit of light. Here’s why that matters for perception.
