a When photon-pair generation is probabilistic, a two-photon interference measurement between A2 and B1 alone cannot distinguish successful events from unsuccessful ones. Therefore, additional ...

Scientists in Japan have developed a new way to instantly detect elusive quantum “W states,” a major milestone for quantum technology. The breakthrough could help unlock faster quantum communication, ...

Record entanglement swapping—rates of 1.7M+ pairs/hour (local), leveraging Qunnect's high-fidelity entanglement sources and polarization compensators Room-temperature endpoints enable scalable ...

A programmable photonic circuit has been developed that can execute various quantum algorithms and is potentially highly scalable. This device could pave the way for large-scale quantum computers ...

As long as there's been an internet, there's been a way to hack it. Scientists have spent decades imagining a different kind of network, one where the laws of physics make eavesdropping physically ...

In optical interferometry, waves of a light signal travel to separate light collectors, and the interference pattern formed by superimposing the waves reveals spatial information about the light ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

These results represent the world's first experimental demonstration of entanglement swapping via sum-frequency generation between single photons. This achievement marks a significant step forward in ...

Northwestern University engineers are the first to successfully demonstrate quantum teleportation over a fiberoptic cable already carrying Internet traffic. The discovery introduces the new ...
