Qubit ZooExperimental realization of a deterministic universal gate set for finite-energy GKP logical qubits encoded in two motional modes of a trapped ion.
Key Results
- Energy-preserving single-logical-qubit gates with process fidelity as high as 0.960
- First two-logical-qubit GKP entangling gate, with CZ process fidelity of 0.680
- Direct GKP Bell-state preparation from vacuum with logical state fidelity of 0.842
- Optimal spin–motion control preserves the finite-energy envelope of the GKP code words
