Quantum computing isn't much past the "idea" stage. Sure, they can multiply two 2-bit integers, but it takes a dozen grad students a week to set up for the run, and another week to validate the results.

Long-term it's probably got a lot of potential, though it may never be stable enough for use outside of a highly controlled lab-based "supercomputer" environment.

At this point I'd classify it more as Physics than Computer Science. In a way, it's as if Charles Babbage got his hands on one of Michael Faraday's papers and started thinking about maybe, possibly, someday, being able to use electromagnetism as a basis for calculation.

There's been a fair amount written about Quantum Computing over the last couple of years in Scientific American, much of it by the primary researchers themselves: <a href="http://www.sciam.com" rel="nofollow noreferrer">http://www.sciam.com</a>

blocks|key|4110191|text|据我所知，纠错和相干损失是量子计算中的大问题。许多聪明人都在努力解决这些问题，但我最近读到的是，纠错要求可能比qbits的数量呈指数级增长，这真的有损于“我们马上就能解决NP问题！”量子计算的吸引力。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4110192|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Error correction and loss of coherence are the big problems in quantum computing, as I understand it. Lots of smart people are hard at work on solving these problems, but last I read, it was looking like error-correction requirements might be exponential over the number of qbits, which really detracts from the "we'll solve NP problems in an instant!" attraction of quantum computation.

Quantum computing is a tool; it's just a tool too raw to have any sort of useful application as of this moment, but who knows.

Nice, I get to re-use my <a href="https://stackoverflow.com/questions/432922/significant-new-inventions-in-computing-since-1980/5161092#5161092">answer from another SO question</a> word-by-word. :)

A few answers mention quantum computers as if they're still far in the future, but I beg to differ.

There were vague mentions of possibility of quantum computers in 1970s and 1980s (see <a href="http://en.wikipedia.org/wiki/Timeline_of_quantum_computing" rel="nofollow noreferrer">timeline on Wikipedia</a>), however the first "working" 3-qubit NMR quantum computer was built in 1998. The field is still in infancy, and almost all progress is still theoretical and confined to academia, but in 2007 company called D-Wave Systems presented a prototype of a working 16-qubit, and later during the year 28-qubit adiabatic quantum computer. Their effort is notable since they claim that their technology is commercially viable and scalable. As of 2010, they have 7 rigs, current generation of their chips has 128 qubits. They seem to have partnered with Google to find interesting problems to test their hardware on.

I recommend <a href="http://www.youtube.com/watch?v=56qR0iX5A4o" rel="nofollow noreferrer">this short 24-minute video</a> and <a href="http://en.wikipedia.org/wiki/D-Wave_Systems" rel="nofollow noreferrer">Wikipedia article</a> on D-Wave for a quick overview, and there a lot more resources on <a href="http://dwave.wordpress.com/" rel="nofollow noreferrer">this blog</a> written by D-Wave founder and CFO.

I have recently been web-researching quantum computing. 

Will we see these in our lifetimes (ever?) (The error correction issue, for example, seems intractable to me).
