Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more ...

A team in China has demonstrated the simultaneous teleportation of multiple sideband qumodes in a continuous-variable system, overcoming a longstanding technical barrier.

So scientists found a workaround. Instead of building one gigantic telescope, they placed smaller telescopes far apart and combined their light. If done correctly, the system behaves like a single ...

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...

Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have made a significant discovery regarding quantum entanglement. This phenomenon, which has long been viewed as a ...

By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

A recent theoretical study by an international team, which also involves the National Institute of Optics of the National Research Council (Cnr-Ino), proposes an innovative method to generate ...

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

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is ...
