A nano-hologram recorded within the interference patterns of quantum electron waves
Stanford University researchers have encoded an electron wave quantum hologram to display letters. The yellow area is a copper surface. The holes in the copper are molecules of carbon monoxide. Constantly moving electrons on the surface of the copper bounce off the carbon monoxide molecules in predictable ways. With their dual wave/particle properties, the electron waves in the purple area create inference patterns that can store readable information, in this case, the letters S and U. To store the data, the researchers arrange the molecule in specific patterns with a scanning tunneling microscope ... more
