Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

The continuous development of bright, stable and highly coherent high-energy light sources is a propellant to the fields of material science, biomedical imaging, ultrafast spectroscopy, and industrial ...

Scientists have achieved a breakthrough in light manipulation by using topological insulators to generate both even and odd terahertz frequencies through high-order harmonic generation (HHG). By ...

Physicists have managed to simulate a strange quantum phenomenon where light appears to arise from empty space a concept that until now has only existed in theory. Using cutting-edge simulations, ...
