This research addresses a critical bottleneck in universal quantum ecosystems by redesigning device models to accurately represent neutral atom capabilities like dynamic qubit rearrangement. By correcting assumptions inherited from superconducting architectures, this approach reduces compilation routing overhead fidelity requirements by up to 100,000 times for specific circuits. The work is essential for enabling seamless integration of emerging neutral atom hardware into standard frameworks such as Qiskit and Cirq.

Quantum Device Model Rethink Cuts Neutral Atom Compilation Overhead 100,000×

Quantum ZeitgeistJuly 26, 20266 min read

Universal quantum ecosystems, such as Qiskit, Cirq, and PennyLane, currently use device models shaped by superconducting hardware, preventing representation of neutral atom devices’ dynamic qubit rearrangement and zoned operations. This limitation hinders integration of neutral atom devices, leading to suboptimal compilation results, but a rethinking of current device models can unlock a routing overhead fidelity improvement by a factor of up to 100,000 on a circuit with 16 qubits and 600 gates.

A redesign of device models for neutral atom quantum computers has achieved a routing overhead fidelity improvement by a factor of up to 100,000, addressing a critical barrier to wider adoption of the technology. Universal quantum ecosystems such as Qiskit, Cirq, and PennyLane rely on device models historically shaped by superconducting hardware, which assume static qubit positions and fixed coupling maps. This prevents them from representing the unique computational capabilities of emerging technologies such as neutral atoms, which feature dynamic qubit rearrangement and zoned operations. As a result, although numerous specialized compilers for neutral atom devices already exist, they cannot retrieve the hardware information they…
