Hardware Implementation of a Hybrid Transport and In-Place Entangling Architecture for Neutral Atom Quantum Computing

We demonstrate the hardware implementation of a hybrid transport and in-place entangling architecture on Infleqtion's Sqale QPU, a neutral-atom platform whose architecture reduces motion overhead while preserving high-fidelity gates and all-to-all connectivity. This architecture integrates atomic motion control with site-resolved, in-place Rydberg entangling operations to overcome transport throughput-latency and motion-related decoherence inherent in zone-based shuttling systems. We describe the hardware implementation, performance metrics, and ongoing system improvements. Combined with Superstaq compiler-level optimization, this platform achieves better logical-than-physical performance across a set of compiled quantum circuits, including a logical realization of Shor's algorithm, constant-depth CNOT ladder operations, and initialization of the [[16,4,4]] many-hypercube code. This co-designed hardware–software approach establishes a foundation for scalable, fault-tolerant neutral-atom quantum computation.
