Quantum light sources emitting triggered single photons or entangled photon pairs have the potential to boost the performance of quantum key distribution (QKD) systems. Proof-of-principle experiments affirmed these prospects, but further efforts are necessary to […]

Engineers at Caltech have shown that atoms in optical cavity could be foundational to the creation of a Quantum Internet. The researchers constructed a nanophotonic cavity, a beam that is about 10 microns in length […]

An international team has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The team has developed a new method for generating and detecting quantum-entangled photons […]

Harvard and MIT researchers have found a way to correct for signal loss with a prototype quantum node that can catch, store and entangle bits of quantum information. The research is the missing link towards […]

A team from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) first realized distribution of high-dimensional orbital angular momentum entanglement over a 1 km few-mode fiber. The orbital […]

Researchers at University of Bristol, UK, have demonstrated new chip-based devices that contain all the optical components necessary for quantum key distribution while increasing real-world security. This fast and cost-effective platform is poised to facilitate […]

Researchers at the University of Science and Technology of China and Tsinghua University have recently achieved an unprecedented quantum key distribution (QKD) transmission distance using the SNS-TF protocol. The sending-or-not-sending twin-field (SNS-TF) protocol has so […]
