POQUET

POQUET is a proposal with Dario Gerace and Daniele Sanvitto to secure funding to build a deterministic, high-fidelity quantum computer. Its first version was submitted to a bilateral CISC-CNR call on 15 September (2025) for networking, still with the promise of realizing a deterministic, high-fidelity CNOT gate!

No details so far but a list of references from the proposal. Tell me who you cite, I'll tell you what you want to do.
