Physicists have observed a novel quantum effect that limits the number of emitted photons, outlines a new report. The probability to find a certain number of photons inside a laser pulse usually ...

Physicists at the Max Planck Institute have developed an efficient new method to drive the quantum entanglement of photons, and demonstrated it by entangling a record number of photons. The technique ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

One of the less satisfying aspects of modern physics is the increasing separation between the phenomena that we measure and the experimenter. We measure almost everything today indirectly. If we ...

Pulses of light comprising around 100,000 entangled photons have been created by physicists in Germany and Russia. The pulses were made in the “squeezed-vacuum” state and the team found that the ...

Physicists in Israel are the first to entangle five photons in a NOON state – the superposition of two extreme quantum states. Unlike previous schemes for creating such states, the researchers claim ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...
