In classical computer science, information is stored in bits; in quantum computer science, information is stored in quantum bits, or qubits. Experiments at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw prove that chemistry is also a suitable basis for storing information. The chemical bit, or 'chit,' is a simple arrangement of three droplets in contact with each other, in which oscillatory reactions occur.
In typical electronic memory, zeros and ones are recorded, stored and read by physical phenomena such as the flow of electricity or the change in electrical or magnetic properties. Dr. Konrad Gizynski and Prof. Jerzy Gorecki from the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw have demonstrated a working memory based on chemical phenomena. A single bit is stored here in three adjoining droplets, between which chemical reaction fronts propagate steadily, cyclically, and in a strictly defined manner.
The chemical foundation of this form of memory is the Belousov-Zhabotinsky (BZ) reaction. The course of the reaction is oscillatory. When one cycle ends, the reagents necessary to start the next cycle are reconstituted in the solution. Before the reaction stops, there are usually several tens to hundreds of oscillations. They are accompanied by a regular change in the colour of the solution, caused by ferroin—the reaction catalyst. The second catalyst used by the Warsaw researchers was ruthenium. The introduction of ruthenium causes the BZ reaction to become photosensitive—when the solution is illuminated by blue light, it ceases to oscillate. This feature makes it possible to control the course of the reaction.
"Our idea for the chemical storage of information was simple. From our previous experiments, we knew that when Belousov-Zhabotinsky droplets are in contact, chemical fronts can propagate from droplet to droplet. So we decided to look for the smallest droplet systems in which excitations could take place in several ways, with at least two being stable. We could then assign one sequence of excitations a logic value of 0, the other 1, and in order to switch between them and force a particular change of memory state, we could use light," explains Prof. Gorecki.

marketing guy deciding that he can advertise more capacity if a kilochyte is 1000 and not 1024 chits in 3..2..1..

And then we have the "tits". Very much a system depending on oscillatory motion. Predicting what will happen next based on proximity is fairly easy :)

RT reports that Russian physicists are working on closing the "chit gap" with NATO superpower Poland by perfecting Nuclear Isotope memory bits, or "nits". Moscow University is now offering special research fellowships to gifted researchers, known as "nit wits".
So far, the technology has only been demonstrated in the remote Vladivogoyinskayaveromorsk Cold-Fusion Perpetual Antimatter Generator facility, but a serious radiation leak has led to nit wit fallout contamination of North Korea.
North Korean sources deny the report, saying that "The DPRK's dear leader himself is the inventor of nit wit technology, and soon fiery nit wits will rain down on our Capitalist enemies!"
Meanwhile, the BBC is reporting that 10 Downing has issued a dismissive statement noting that Britain has been secretly mass-producing nit wits at Westminster for many years.

The assemblage of letters that comprise "qubit" form a nonsensical word and can not be pronounced "cue bit" as, presumably is the intention. The correct word and spelling for a quantum computing bit is Qbit, ala Xray. "Qu" makes a "kw" sound.
