The US National Security Agency is developing a quantum supercomputer capable of cracking virtually any encryption system ...
...
Other computational algorithms will allow the quantum computer to decompose numbers into prime multipliers at an enormous speed and thereby crack ciphers of any complexity.
Bullshit. Factorization or prime factorization will only break RSA ciphers. The rest of the public key cryptography is based on the problem of discrete logarithm modulo a large prime number. And prime numbers don't have prime factors because they are only divisible by themselves or by 1 without a remainder.
Quantum computers have been implemented since the last century. Only their computational capabilities are still much worse than the usual microcalculator. I.e. such crap can decompose into factors only number 15, and that if one is very lucky, but it consumes an awful lot of electricity and requires super-duper sophisticated protection against interference.
At least Bitcoin is not threatened by quantum computers, because its cryptography is based on ECDSA, not RSA.

I have a lamp calculator somewhere (a lamp is used to display information).
I also have a calculator ), at the local supermarket I still use it to count.)

Quantum computers can be used for more than just number factorisation: http://arxiv.org/pdf/quant-ph/0301141v2.pdf
It is hoped that if a real quantum computer is created, bitcoin cracking will be invisible from the rest of the problem.
Threw a little party at the office

Why is only bitcoin praised here?
because the thread is about bitcoin, it's obvious.)
ZS: And it's not just praising bitcoin, it's also criticising it.
