IQOQI new 5-atom quantum computer could make today's encryption obsolete

Summary: 

A realization of a scalable Shor algorithm, as proposed by Kitaev, is presented, factoring the number 15 by effectively employing and controlling seven qubits and four “cache qubits” and by implementing generalized arithmetic operations, known as modular multipliers.

The algorithm has been realized scalably within an ion-trap quantum computer and returns the correct factors with a confidence level exceeding 99%.
