The power of quantum computers

Integer factorization is believed to be practically impossible with an ordinary computer for large numbers that are the product of two prime numbers of roughly equal size (eg. products of two 300-digit primes). By comparison, a quantum computer could solve this problem very quickly. If a number has n bits (is n digits long when written in the binary numeral system), then a quantum computer with just over 2n qubits can find its factors. It can also solve a related problem called the discrete log problem. This ability would allow a quantum computer to break many of the cryptographic systems in use today. In particular, most of the popular public key ciphers could be quickly broken, including forms of RSA, ElGamal and Diffie-Hellman. These are used to protect secure Web pages, encrypted email, and many other types of data. Breaking these would be significant.

2.I read that this computer if sucessful,can make all conventional computers
like a toy.Have u seen SNEAKERS by Robert Redford.exactly the same.With the magic box,they can break in US DOD etc.The real one off course may be bigger in the initial stage.
3.Who get this wil sure know all secret.
Dunt worry,We are also RD something......!ha ha ha!
We have teams leaded by top expert in this subject.u cannt believe this!

Read more and tell us how is the development in the world in this two fields.
Are they in fact the same thing?
