IBM Builds A Limited Quantum Computer
phr1 writes "IBM has announced and Yahoo has noted that the first working implementation of Shor's
factoring algorithm. Using NMR techniques they built a seven-qubit
quantum computer and factored the number 15 into the factors 3 and 5.
This is by far the most complicated quantum computation ever done.
It's quite an amazing feat--many people thought quantum computing
was just a theoretical curiosity and Shor's algorithm could never
be implemented in practice."
Looks like the number of qbits available in a quantum computer is doubling every 18 months. The article notes the 2 qbit computer was built in 1998, the 4 qbit unit in August 2000 and now a 7 qbit computer in December 2001....they've still got another couple of months to get the 8th qbit....
