Italy planned to inaugurate Volta B1 in Como on Friday, Oct. 16, and its 4,400-plus qubits do not by themselves show it can break blockchain signatures.
Volta B1 uses D-Wave's Advantage2 design and contains more than 4,400 qubits. Its annealing method tackles optimization problems, but the count alone offers no evidence that the system can crack the signatures used by blockchain networks. Italy also has a separate 140-qubit neutral-atom system at CINECA, installed in June.
An earlier EconoTimes report on Volta B1's arrival in Lombardy identified Villa Saporiti in Como as the planned installation site.
Three standards addressing post-quantum cryptography have been finalized by the National Institute of Standards and Technology (NIST), including two for digital signatures. The agency recommends organizations begin adopting them.
Aztec's network cryptography transition plan has a year-end 2030 completion target and relies in part on Ethereum upgrades.
