Researchers Create Silicon-Based Quantum Bit

No, they've demonstrated a single Qubit.

TFS makes things mucky by mentioning single electron transistors too, which are a completely different beast.

The problem with quantum computing isn't demonstrating single qubits though. The problem is in getting a reasonable number in a superposition. Most I've ever seen in a QC that actually does computations is 7 qubits.

Just to get an idea of the scale we need, Shor's algorithm, the one which we could use to crack RSA encryption in polynomial time, needs 2*N qubit
