Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional ...

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 ...

Scientists used entangled X-ray photon pairs to produce ghost images of tiny samples, a proof of concept that could enable longer, lower-dose studies of delicate biological materials.

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark photons to be considered serious candidates for dark matter, with promising ...

“Molecules” made from three photons have been created by physicists in the US. The photon triplets were made by firing laser light into an atomic gas and the researchers believe that their technique ...

"When a particle moves through spacetime, how do we know it is the same particle and not some excitation that is passed from place to place?" We don’t! This is a really interesting feature of our ...

I have completely lost count of how many times I have read phrases like, “Consider a light source that emits photon pairs that are indistinguishable.” This indistinguishability, along with the ability ...

Using photonic chips to control single photons in waveguides is a promising route to technologies based on the photons'quantum properties. The ability to measure entanglement on such chips is a key ...

Why do we call photons 'particles'? Aren't they all electromagnetic waves? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better ...
