Da li je dosad napravljen kvantni racunar i ako neko nesto vise zna neka kaze?

Napravljen? Hmm, teško. Pokušaji i studije postoje, ali ono što je dosad urađeno nije maklo mnogo dalje od čistog teoretisanja.

cini mi se da su izraelci najvise tu uradili

Znam da je teoretski napravljeno dosta (algoritmi shora, Groovera, itd), i da im je za hradver najveci problem hajzenbergov princip neodredjenosti sto je i logicno, ali sam isto tako cuo (osoba koja mi je rekla je jedna od najbojljih programera koje sam ja vidio uzivo) da je napravljen neki sa nekih 2-3 bita i da ima veze sa ovom nuklearnom magnetnom rezonancom. Jednostavno me interesuje da li je to istina i ako jeste naravno jos nesto da se zna?

D-Wave je razvio računar za komercijalnu upotrebu za koji tvrdi da je prvi kvantni računar. Imajući u vidu ko su kupci evidentno se radi o ozbiljnoj kompaniji. (kupci D-wava su: D wave one je kupio Lockheed Martin, a zainteresovan je i za D Wave 2 koji su već kupili NASA i Google zajedno. Google i NASA su D wave kupili za Quantum Artificial Intelligence lab. A evo kako je testiran: "The new Quantum Artificial Intelligence lab also put the new D-Wave Two through rigorous testing before accepting the machine, according to a Google representative. One particular test asked the computer to solve certain optimization problems at least 10 000 times faster than classical computer solvers. In another case, the D-Wave machine set the highest scores on standard problems used in SAT competitions."

Nije taj D-Wave bas tako kvantni izgleda:
http://www.bbc.com/future/stor...-big-bets-on-quantum-computers

"However, unlike most computers, D-wave’s machines, cannot answer any old question. Instead, it is only able to solve so-called “optimisation” problems, where there are a series of criteria all simultaneously competing to be met, and where there is one optimum solution that satisfies the majority of them – for example, the optimal route for a delivery truck to drop off packages, minimising the time and distance travelled."

"But in most cases, proving that a quantum computer will actually perform these sorts of functions faster than a classical computer is still in the realm of theory. As it is, not everyone is even convinced yet that the D-Wave computer is actually using quantum mechanics to make the calculations.""
Realno...

The NSA Probably Really, Really Wants a Quantum Computer
How long until the security agency gets one?

This is huge: Physicists have figured out how to reliably transmit quantum information, a major first step toward the kind of quantum communications and quantum computing that would dramatically enhance our ability to secure networks, crack codes, and search databases.

These potential applications of quantum computing—and I'll get to what exactly that means in just a minute—help explain why government agencies ought to be interested in such technologies. And the latest news in this realm is significant. It comes from a team of nanoscience researchers at the Delft University of Technology in the Netherlands, where physicists successfully transmitted encoded quantum information from one computer chip to another, across a distance of about 10 feet.

Abstract

Realizing robust quantum information transfer between long-lived qubit registers is a key challenge for quantum information science and technology. Here, we demonstrate unconditional teleportation of arbitrary quantum states between diamond spin qubits separated by 3 m. We prepare the teleporter through photon-mediated heralded entanglement between two distant electron spins and subsequently encode the source qubit in a single nuclear spin. By realizing a fully deterministic Bell-state measurement combined with real-time feed-forward quantum teleportation is achieved upon each attempt with an average state fidelity exceeding the classical limit. These results establish diamond spin qubits as a prime candidate for the realization of quantum networks for quantum communication and network-based quantum computing.

Bila je skoro emisija na StudioB, naš naučnik Vlatko Vedral koji radi u Engleskoj i Singapuru ako ne grešim i potvrdio je da se uveliko radi na tome i da postoji neka vrsta racunara na kvantnom nivou.

Pricali smo o tome ovde jos 2011. godine. Mala dopuna temi:
