The chemical reaction is incredibly quick, taking less that
a thousandth of a billionth of a second,» said Villy Sundström, Professor of Chemistry at Lund University.
Prof. C David Wright, an expert in electronic engineering and co-author of the study said: «This device is able carry out all the basic functions you'd associate with the traditional abacus — addition, subtraction, multiplication and division — what's more it can do this using picosecond (one -
thousandth of a billionth of a second) light pulses.»
Although neon is a relatively simple atom with a total
of ten electrons, the experiment required both extremely careful timing, with a level
of accuracy within one
billionth of a
billionth of a
second (known as an attosecond), and extremely sensitive electron detection that could distinguish between electrons whose speed differed only by around one
thousandth of an attojoule (a millionth
of an electron's stationary energy).
