Quantum Computer Could Mean End Of Encryption

Researchers have built a computer that can tackle a fundamental challenge of cracking present-day encryption schemes: factoring large numbers.

The computer uses laser pulses to carry out Shor’s algorithm on each atom, to correctly factor the number 15. The system is designed in such a way that more atoms and lasers can be added to build a bigger and faster quantum computer, able to factor much larger numbers. The results, they say, represent the first scalable implementation of Shor’s algorithm.
