The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement swapping (one of the key quantum communication protocols) using sum-frequency ...

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 at Sandia National Laboratories and the Max Planck Institute have developed a way to produce a web of quantum entangled photons using a far more simple setup than usual. The key is a ...

New device emits photons in telecom fiber band from the start, so it avoids a separate converter that can waste photons.

In a groundbreaking achievement, scientists have successfully captured the precise shape of a single photon, marking a significant advancement in quantum optics. This milestone, achieved through ...

Theoretical physicist Alex Lupsasca is pushing for a space telescope to glimpse the thin ring of light that is thought to surround every black hole.

Researchers have been developing computers that deploy light (photons) rather than electricity to power storage and ...

Physicists have described in theoretical terms how to develop codes that cannot be broken by quantum computers -- computing devices of the future. These codes rely on distributing single photons that ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

For governments and corporations in the business of transmitting sensitive data such as banking records or personal information over fibre optic cables, a new system demonstrated by University of ...
