        <description><![CDATA[The Times quote &quot;... make it possible to factor large numbers more quickly ... undermining modern data-scrambling systems&quot; is alarmist. If encrypted code can be factored more easily, that simply means keys will need to grow accordingly and encryption will also operate that much faster. It will be feasible, then, to encrypt everything. The transmission of information will still be the bottleneck.]]></description>

        <description><![CDATA[This seems to be more of a proof of principle rather than an initial prototype that now needs to be manufactured. From a few minutes of googling and reading (and watching the included video) I see &quot;...method of manipulating at the atomic scale can form the basis for quantum computers, machines that use the effects of quantum mechanics, specifically the spin of electrons around an atom, to represent digital information.&quot;I'm guessing it's the eventual using of the electrons of the atom in question that will represent the data written and stored that defines this &quot;single&quot; atom as a transistor. At this scale &quot;components&quot; seem more defined by function than form. Consider that an atom isn't a single object but composed of many many many subatomic components and maybe someday will count for a number of components within a device while remaining just a &quot;single&quot; atom. Imagine when we can incorporate all the subatomic structures and energies within an atom into our devices.Obviously a single atom is just an element and by itself can't do anything other then just be that element in relationship with the environment around it. When the atom can be placed very precisely, that placement in itself is information, structure, and organization.  Think about it some more and lighten up a bit.]]></description>

        <description><![CDATA[At this point, its a toy, kind of like the itty-bitty motor they made.You make these things by moving atoms around.  Unless they make some formof lithography to generate the &quot;chip&quot; it would take years to make just a singlechip of any serious power.  The other problem is you still have to deal with theinterference factors if the atoms are too close.  The tunneling problems if thewires are too thin, etc.The next &quot;REAL&quot; advance I see is some form of 3d Lithography that will allow moreefficient circuits be built in a cube form vs the almost 100% flat form we have now.]]></description>

        <description><![CDATA[Hi dduggerbiocepts,I stated that it was embedded in its silicon bed. If you want more details on exactly how it works, the SF Chron/Bloomberg story, which is titled &quot;Transistor Made Using a Single Atom May Help Beat Moore's Law&quot; states, &quot;The atom was etched into a silicon bed with 'gates' to control electrical flow and metallic contacts to apply voltage.&quot;  The Times story, which is titled &quot;Physicists Create a Working Transistor From a Single Atom,&quot; gives some background on recent advances that led up to this one: &quot;There have been a series of recent technical advances that suggest that engineers will not hit a wall ending the advance in computer performance any time soon. In January, the Purdue and New South Wales researchers reported in the journal Science that they were able to create silicon nanowires that were just a single atom thick and four atoms wide by assembling thin strands of phosphorus atoms.Combining the two advances indicates that they have made progress at assembling the basic building blocks of a new ultra-small generation of nanoelectronics that would be assembled from the bottom up.&quot;Laura]]></description>

        <description><![CDATA[Transistor from a single atom? Shin - didn't you read what you wrote?  What about all the other stuff that had to be added to make a the phosphorus atom a functioning transistor? The phosphorus atom might be the single critical component in the transistor, but it would not function without it's silicon bed of many silicon atoms. Thus the phosphorus atom by itself if does not represent a functioning freestanding transistor &quot;made of one atom.&quot; Reporters should really take more logic classes and focus on greater accuracy in their communication skills.]]></description>
