D-Wave Advantage2 at SQT Como
D-Wave Advantage2 at SQT Como is a quantum annealing quantum computer operated by Swiss Quantum Technology in Italy. It has 4,400 physical qubits. It ranks 1 of 6 annealing machines in this table by physical qubit count. 3 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as SQT Advantage2, Q-Alliance D-Wave system
Swiss Quantum Technology SA committed EUR 10 million in October 2025, which Quantum Computing Report says buys 50 percent of the machine time for five years with an option to purchase the system. The system is to be reachable through D-Wave's Leap cloud and supports Italy's newly formed Q-Alliance. No delivery date was announced and no installation report was found, so it is recorded as planned.
Spec sheet
Technical details as the builder or a paper states them, each with its own source. A blank is a fact we could not source, not a zero. Fidelity and coherence figures are in the benchmark table below.
