The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, ...

As quantum computers continue to advance, many of today's encryption systems face the risk of becoming obsolete. A powerful ...

Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international collaborators, have developed two complementary methods that could make quantum ...

Can quantum optics be used for practical applications? A lot depends on whether a large number of photons can be gathered in quantum state. Among all quantum systems, photons are known for their weak ...

With an applied physics: optics degree, you’ll gain specialized expertise in optics, preparing you for diverse career opportunities in technology, research, and academia. Become who you’re meant to be ...

In collaboration with Sony, the National Institute of Information and Communications Technology developed an electrically driven VCSEL that operates at 1,550 nm. This is the standard wavelength used ...

Quantum-enhanced measurement schemes promise sensitivities beyond the shot noise limit, but their practical implementation in atomic systems has long ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...
