Can atoms/molecules store informations?

[kumar5]

Hello,

I was just thinking that many type of energies might be interacting with atoms and molecules. As such, are/can they keep the informations their interactions with energies (non-chemical reaction based) for long? So;

Can atoms and molecules store informations of "non-chemical reaction based" interactions with these? If yes, How?

Can it be by some variations in their structure or motions showing variations in their absorbed, emited or reflected energies/spectrum/wave-lengths OR by some degradation of atoms/molecules as a natural process? Whether every atom/molecule of same element/composition have absolutely same absorption, emission or reflection levels?

In short, are different atoms/molecules of same element/substance are absolutely same or not?

I am not asking/considering isotopes.

Best wishes.

yes, an atom with certain spins (electrons and nucleous spins) would have slightly different spectrum lines then the same atom with different spins (though the time the base energy is above ground is very short),
you could also change the levels of energy by putting the atom in a magnetic field, this change is constant as long as the field exist, so it can store long term info.

atom storing information is called Qubit, and by Fourier transform you can take the most probable state of it and say that's it's state.
there are even some logical gates that make calculations between two Qubits.

search Qubit for more information - there are variety of ways to do it...

Hello fargoth.

Thanks.

About atoms in Magnetic field, can electrons persist for long in higher state of their base orbitals--or partly excited? If yes, if atoms are kept above ground..at different position of gravity, stii there will be some change in their vibrations or energy states?

I got link about "Qubit"
http://en.wikipedia.org/wiki/Qubit

Is it not related to computer informations?

fargoth,

Suppose we keep two atoms or molecules of different element/substance close together and maintain such contact. Will these be remain effected by each other by their changed spins and spectural lines?

The first MRAM chip assembly line just got started up today. You might want to take a look into that.

A non-trivial problem with most qubit systems is the tiny, tiny coherence times!

Magnetoresistive Random Access Memory (MRAM)
Description
Unlike conventional RAM chip technologies, data is not stored as electric charge or current flows, but by magnetic storage elements. The elements are formed from two ferromagnetic plates, each of which can hold a magnetic field, separated by a thin insulating layer.
http://en.wikipedia.org/wiki/MRAM

it involve ferromagnetic substances. What about other substance? Whether all non-ferromagnetic substance can also effect each other and store information, 1. if close contact is maintained 2. or if discontinued?

 

[kumar5]

Pl tell me about magnetic field or other effecting fields of non-ferromagnetic substances(both) to other substance which may alter spins and spectral lines even thought slightly. Pls tell such effects by keeping one substance in close contact to other in its natural form and by dilutinf or induvidualising its molecules?

if atoms store energy, where do they do it physically? where is it's brain?
