BSC presents the first quantum computer in Spain developed with 100% European technology

In the sense that there are usable qubits, and single and two qubits gates that one needs in computations, it does work. Presently coherence times are too short and number of qubits too low for practically useful computations, though.

Regardless, a lot can be learned in projects like this about integrating conventional and quantum computing. One has to start somewhere.

They’ll be implementing several updates over the coming years to push towards useful computations. The engineering challenges are formidable and the road will be long and bumpy.

Yes and no.

Yes and No? Depends on how you look at it.
