Quantum computing

Quantum Computing is a field on which research is being done. It is a very promising field, as the advances in this field can increase the computing power of todays computers tenfold ( actually much more than that). The concept behind quantum computing is a bit hard to understand. I couldn't figure much about it. Quantum computers should be able to crack most of the current prevalent encryption standards such RSA etc pretty easily.In 1999, a group from Los Alamos National Laboratory and MIT constructed the first experimental demonstrations of a quantum computer using nuclear magnetic resonance (NMR) technology.Though these devices have had mild success in performing interesting experiments, the technologies each have serious limitations.
