Electronic quantum holography (also known as quantumholographic data storage) is aninformation storage technology which can encode and read outdata at unprecedented density storing as much as 35bits perelectron.[1]
In 2009,Stanford University's Department of Physics set a new world record for the smallest writing using ascanning tunneling microscope and electron waves to write the initials "SU" at 0.3nanometers, surpassing theprevious record set by IBM in 1989 usingxenon atoms. This achievement also set a record for the density of information. Before this technology was invented the density of information had not exceeded one bit per atom. Researchers of electronic quantum holography however were able to push the limit to 35 bits per electron or 20 bits nm−2.[2]
Acopper chip is placed in a microscope and cleaned.Carbon monoxide molecules are then placed on the surface and moved around. When the electrons in copper interact with the carbon monoxide molecules, they create interference patterns that create an electronic quantum hologram. This hologram can be read like a stack of pages in a book,[3] and can contain multiple images at differentwavelengths.[4]
