IQM Quantum Computers Garnet: Q-score
15 Q-score
As stated in the source: “Q-score of 15”
Caveats
Uses the virtual-node trick (score of 15 on 14 qubits), so not directly comparable with Q-scores obtained without it. Company-run, not peer-reviewed.
- Set-up
- Depth-1 QAOA; the virtual-node technique solves a size-n problem on n - 1 qubits and raises the score by 1.
- Method
- Atos Q-score (Max-Cut on Erdos-Renyi graphs, p = 0.5), depth p = 1 QAOA, pass threshold beta(n) >= 0.2, with one virtual node
- Compared only with
- results in the group “gate based qaoa p1”
