“Despite being considered well established, the physics of optical waves have some fundamental aspects, which are still under debate. One of these effects, the anomalous behaviour of focused light fields, has now been investigated in a new light, a quantum …
“Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the colour of a pulsed laser, the team can track changes in the spectrum of the light by simple …
“Researchers at Tampere University Photonics Laboratory have demonstrated how two interfering photons can bunch into various shapes. These complex shapes are beneficial for quantum technologies, such as performing fast photonic quantum computations and safe data transfer. The method opens new …
