Quantum Programming with Perl

Developers looking to keep their skills current well into the next decade should check this out ;) Debian folks can grab libquantum-entanglement-perl and libquantum-superpositions-perl."

For one thing, QCs do exist - in fact, they demonstrated Peter Shor's 1994 factoring algorithm on a recently built 7-qubit box, factoring 15 into 3 and 7.

I wouldn't get too exited about this. Shor's factoring algorithm is a probabilistic algorithm, and for a small number such as 15 you could replace the entire quantum part by rolling some dice and still manage to find factors. So it's possible that the demonstration you refer to messed up somewhere but still managed to factor 15.

Also, NMR quantum computing (which was used for that demonstration) is fundamentally limited to a maximum of around 12 qubits, and I seriously doubt the NSA has got anywhere near 10.

Secondly, the Heisenberg uncertainty principle only states that you can't predict with 100% accuracy which eigenstate a qubit will collapse into upon measurement

This is not the Uncertainty principle. This is the measurement postulate.

The Heisenberg uncertaintly principle says things like " if you know the position of a particle precisely then you can't know anything about it's momentum" etc. Or, to wax technical, the products of the "errors" for position and momentum being greater than half the expectation value of the commutator of the operators represneting position and momentum.
