Advancements in quantum information technology are paving the way for faster and more efficient data transfer. A key ...

Deciphering the information within a light field through one photodetector is challenging. Scientist in China have reported a ...

Waves in water are transverse. This means that the vibrations causing the waves are perpendicular to the direction of energy transfer. As this little boat demonstrates, you can see that the waves ...

The extent of the spreading (diffraction) depends on how the width of the gap compares to the wavelength of the waves. The wavelength is unchanged after diffraction. A gap width similar to the ...

Researchers have developed a promising new optical memory technology using rare earth elements and quantum defects to enable ...

The bulk photovoltaic effect (BPVE), known for overcoming the Shockley-Queisser limit, typically operates within a narrow ...
