Sydney researchers demonstrate a universal gate set on GKP qubits

Sep 9, 2024

Researchers encode two logical qubits in a trapped ion’s motion and demonstrate a universal gate set. Their first preprint reports 68% process fidelity for the entangling gate, a proof of control rather than fault-tolerant computation.

Why it matters

Entangling encoded oscillators adds the missing two-qubit operation to this hardware-efficient approach to quantum computing.
