Researchers create single-atom silicon-based quantum computer

An artist's rendition of the single phosphorous atom (red circle) surrounded by its electron cloud
A team of Australian engineers is claiming it has made the first working quantum bit (qubit) fashioned out of a single phosphorous atom, embedded on a conventional silicon chip.
This breakthrough stems all the way back to 1998, when Bruce Kane — then a University of New South Wales (UNSW) professor — published a research paper on the possibility of phosphorous atoms, suspended in ultra-pure silicon, being used as qubits. For 14 years, UNSW has been working on the approach — and today, it has finally turned theory into practice.
To create this quantum computer chip .. https://newsroom.unsw.edu.au/quantumbreakthrough , the Australian engineers created a silicon transistor so small that “electrons have to travel along it one after the other.” A single phosphorous atom is then implanted into the silicon substrate, right next to the transistor. The transistor only allows electricity to flow through it if one electron from the phosphorus atom jumps to an “island” in the middle of the transistor. This is the key point: by controlling the phosphorus’s electrons, the engineers can control the flow of electricity across the transistor.
At this point, I would strongly recommend that you watch this excellent video that walks
you through UNSW’s landmark discovery — but if you can’t watch it, just carry on reading.
[ well worth watching for EVERYONE! .. LOL .. IT'S GREAT! ]
To control the phosphorus atom’s electrons, you must change their spin, which in this case is done by a small burst of microwave radiation. In essence, when the phosphorus atom is in its base state, the transistor is off; it has a value of 0 — but when a small burst of radiation is applied, the electrons change orientation, one of them pops into the transistor, it turns on; it has a value of 1.

Now, we’ve written about quantum computers before — the University of Southern California has created a quantum computer inside a diamond .. http://www.extremetech.com/extreme/125221-scientists-create-quantum-computer-in-a-diamond , for example — but the key breakthrough here is that UNSW’s quantum transistor has been fashioned using conventional silicon processes. Rather than beating its own path, UNSW is effectively riding on the back of 60 years and trillions of dollars of silicon-based electronics R&D, which makes this a much more exciting prospect than usual. It is now quite reasonable to believe that there will be readily available, commercial quantum computers in the next few years.

h24, "and the trash" .. duh .. uh uh .. no .. trash is your invention was the thought .. your use of trash lead me to ..
[ one other bit .. hummm, much more excerpted here than i'd felt couple of
seconds before .. lol .. is interesting and i'd forgotten much of it .. ]
The science of ethnography came into the language. On one hand, a science of stereotypes was evolving throughout the nineteenth century, and on the other a culture of categorization was proliferating amongst the competing groups. Colloquial insults took on national and archetypal significance.
White trash was a unique case within this larger culture of systemic racism. Everyone was non-white by virtue of the fact that they were poor, because by definition to be white was to be economically, socially and biologically superior. It came into especially strong favor during the years of the American Reconstruction shortly following the American Civil War. During these years a great deal of political effort was behind the idea of land redistribution, because it was theorized by northern law makers that the power of the southern aristocracy lay primarily in their control of the land. President Andrew Johnson, a Tennessee Democrat, strongly opposed these changes, and the "carpetbaggers" who came down from the north to implement Congress’ redistribution plan. It was at this time that the classic division between poor whites and poor blacks was exploited by land owners.
[GEE .. LAND REDISTRIBUTION .. SCARY!!! lol TERRIBLY SUBVERSIVE RECONSTRUCTIONIST SOCIALISM ROARED INTO THE USA JUST AFTER THE CIVIL WAR ..wow!! .. it's a worry ROTF! .. sorry it just seems so funny .. this attitude thing]
And white trash then became the broad popular lexicon. It became a group identity used widely in discussing race politics for the next 150 years. Within this structure there were Whites, Blacks, White Trash and other non-whites. Over the years it became a concern of choosing sides. Many immigrant groups who had originally been identified as non-white before the Civil War (the Irish are a prime example), quickly began to assimilate in the face of the growing post-war Anti-Black focus. As the ranks of the rich white upper class grew with addition of successful minority "white" groups, so too the ranks of those "whites" who still hadn't succeeded.
It is difficult to define what "white trash" basically means. It is not the definition that is central, but all of the ill-definable jibber jabber which surrounds that "canonical definition" that become important. The context is always growing within the culture.
But cultural definitions are not static. And so, at the moment, it is thought that white trash means something like this:
In the beginning, White Trash was a low-born base-minded rustic; a man of ignoble ideas or instincts; in later use, an unprincipled or depraved scoundrel; a man naturally disposed to base or criminal actions, or deeply involved in the commission of disgraceful crimes. But in fact, that definition had already been set down in the 1300's for another, much earlier word which is not often considered:
1. Villain
1. This term villain was originally, a low-born base-minded rustic; a man of ignoble ideas or instincts; in later use, an unprincipled or depraved scoundrel; a man naturally disposed to base or criminal actions, or deeply involved in the commission of disgraceful crimes.
2. At the outset Villain meant a villager. A citizen of a small town. Nigger literally is a variation on Negro. All it means, literally, is that something is black. White trash, like kike or polack or greaseball, is essentially an empty phrase. As reclamationists have noted, we can fill those cultural words with any content that we want. The definitions have no empirical basis, they have no foundation in the repeatable scientific world of fact. They are instead short-lived, and become more a portrait of a person's heart, and of the culture that they live in.
Anther word that can be used for White Trash is Hillbilly. This term originally came as a pejorative term for people who lived in isolation in the Appalachian Mountains of North America. If one wanted to be less demeaning they would use the term would be "hill folk". The use of this definition was probably correct between the western expansions and the 1940’s. The arrival of the interstate highway system and television brought Appalachian communities into mainstream US culture in the 1950’s, 1960’s, but many communities with relatively traditional lifestyles remain throughout the region.
The hillbilly lifestyle was gently reflected in the 1960’s American sitcom the Beverley Hillbillies.
Today, the term hillbilly means an individual characterized by being generally unrefined.

Every day throughout the world over a billion people rely heavily on Australian invented technologies. Every time they drive a car, fly, prepare a meal, use a laptop or smartphone or spend some time in hospital there is a good chance they are relying on Australian technology. Then you ask people what Australia is famous for and the say “sport”.
