Wow. My information is a bit stale.
The quark system is still under investigation, though it has spun off a rapidly accelerating field of study in the form of qubits.
While the quark was the original model, having theorized states of on, off, and both, the quantum study has gone into qubits, where a particle can
exist in (so far...) 8 states instead of three.
There have already been successful tests of the qubit quantum system. Some interesting facts:
1. The error checking problem in the quark system has been remedied. This was necessary due to the interaction of the non-system which would cause
the entire system to fail.
2. To date, a 12-qubit system has been benchmarked.
3. Using photonic and qubit systems, there has been a preliminary blueprint for teleportation designed.
4. So far, every technology needed for replacing current computers has been researched and developed. The last stage of study for binary replacement
is scaling the sytem to a usable level and then producing the actual integrated system.
This blew my mnd:
Here, we show a combination of all of the fundamental elements required to perform scalable quantum computing through the use of qubits stored in the
internal states of trapped atomic ions. We quantified the repeatability of a multiple-qubit operation and observed no loss of performance despite
qubit transport over macroscopic distances.
THAT is the combined opinions of the seven brainiacks that worked to compile the data. Unfortunately, to get the whole paper, you have to subscribe
to the site. Anyone here help out with it?
The experiment is a "milestone accomplishment," says Isaac Chuang, a professor in the electrical engineering, computer science, and physics
departments at MIT. "Very much like the early evolution of transistors into calculators, this work demonstrates a complete assembly of basic steps
needed for a scalable quantum computer." Chuang adds that the research "sets the bar" for other quantum computing systems.
This was to stabilize the qubits for computational purposes and allow them mobility without interference of outside magnetic fields.
Not only is the quantum computer possible, it is now a reality. We just get to sit and wait it out.
