Global Pulses Address Local Atomic Qubits
A dual-species neutral-atom architecture uses interspecies interactions to avoid locally addressed gates while compiling fault tolerance.
Summary
A dual-species neutral-atom architecture uses interspecies interactions to avoid locally addressed gates while compiling fault tolerance.
The proposed GRAIL instruction set uses two atom species and interspecies Rydberg interactions to select qubits under global driving. The authors compile surface-code correction and magic-state cultivation into that native language, then parallelize schedules to suppress crosstalk. Under a hardware-inferred circuit noise model, crosstalk falls to the 10^-4 level, the memory threshold reaches 1.43 percent and cultivated magic states reach modeled logical error below 10^-9 at an experimentally accessible drive frequency. These are architecture and simulation results, not a completed fault-tolerant computer.
