I would not say that. QC is the implementation of the principles of QM into software programming. Check out John Preskill's webpage for more info on thisTony11235 said:Quantum computing is a broad field,
Nanotechnology and QC do not overlap. Nanotechnology is just another name for quantum many body physics/chemistry on the micro/nano-distance scale.Where nanotechnology and QC overlap is the area where the attempts to "build" ones occur. The progress in that area, I do not know.
The main goal of quantum computing may not be broad, but if somebody says that their research is quantum computing, that doesn't tell you much about what exactly it is they are researching. The field of quantum computing consists of many areas. You can't disagree with that.marlon said:I would not say that. QC is the implementation of the principles of QM into software programming.
Name me five such areas, please.Tony11235 said:The field of quantum computing consists of many areas.
Easy!Name me five such areas, please.

Typical...rachmaninoff said:Easy!
quantum algorithms
quantum information theory
quantum cryptography
quantum error-correcting codes
quantum Teleportation (tangentially)
This is just QM, well many body QM to be exact.Or, if you're an experimentalist:
Trapped ion qubits
NMR qubits
Exciton qubits
Optical cavity qubits
Cavity QED qubits
Great link, thanks!marlon said:Just check out how John Preskill's course is constructed and you will se why all these topics are "dual" to one and other.
When did i ever say that ?rachmaninoff said:QED is just QM?
this is really not true. Error correction is constantly used in encryption and well, the quantum algorithms are the basic ingredient of error correction, encryption,...I mean, we are dealing with "software" here. Do not forget that.Anyway, I listed five experimental approaches to qubits - afaik they pretty much don't intersect at all,

Yeah, but I was referring to the experimental part - the NMR vs. Ion trap vs. optical cavity... they're all different experimental groups, and I doubt they corroborate much.this is really not true.

You were ? Than you should have been more clear. Anyhow, NMR has nothing to do with quantum information technology. It is a technique that might be used for the practical implementation of some of the QIT aspects (encryption, entanglement,...). The same story holds for all the rest.rachmaninoff said:Yeah, but I was referring to the experimental part - the NMR vs. Ion trap vs. optical cavity... they're all different experimental groups, and I doubt they corroborate much.
Yes but this is my point. It is a technique that is used in QIT, but it is NOT a result of QIT. That is the big difference i am trying to illustrate here.rachmaninoff said:NMR has nothing to do with quantum information theory, but if you're talking about quantum computing - which is a practical thing, not the same as theoretical computer science - then it has everything to do with that.
Again, Deutsch's problem is a direct result from coming from QIT (ie the implementation of QM-principles in actual algortihms) but NMR is just used here as an experimental technique. NMR itself is a QM's thing.The group that implemented Deutsch's algorithm a few years ago, they were using NMR.
<semantics war>rachmaninoff said:To clarify: the original post used the words "quantum computing", so I assumed the topic was the most general one, inclusive of the pragmatic, experimental stuff. Regarding QIT, we seem to agree about what it means.

Doesn't quantum computing require working at the atomic level for quantum effects? Is this not "nano"?marlon said:Nanotechnology and QC do not overlap. Nanotechnology is just another name for quantum many body physics/chemistry on the micro/nano-distance scale.
