Carbon nanotubes are moving from lab curiosities to workhorse components in quantum hardware, and one of the most striking examples is their use as single-photon light sources. By exploiting their ...

Polarized light is one of the most powerful tools scientists have for peering inside matter, yet the way it twists, scatters ...

Researchers at the National Institute of Standards and Technology (NIST) have created a tunable superconducting circuit on a chip that can place a single microwave photon (particle of light) in two ...

Artificial intelligence has begun to tackle a task once thought to be uniquely human: designing scientific experiments. And not just any experiments. Researchers at University College London have used ...

Data transmission by laser: The researchers tested data transmission by laser over 53 kilometres from the Jungfraujoch to the Zimmerwald Observatory near Bern. Courtesy: ETH Zürich Researchers in ...

Who’s who: The quantum Alice in Wonderland would like to understand whether the many “Twindeldum-Twindeldees” she sees are really identical or not, and uses the new interferometer for this purpose.

Quantum mechanics, famously, is full of effects that defy our basic intuition. A fine example is the Hong-Ou-Mandel effect, which occurs when two light quanta (or, photons) arrive simultaneously at a ...
