abstract
Quantum computers with a limited qubit connectivity require inserting SWAP gates for qubit routing, which increases gate execution errors and the impact of environmental noise due to an overhead in circuit depth. In this work, we benchmark various routing techniques considering random quantum circuits on one-dimensional and square lattice connectivities, employing both analytical and numerical methods. We introduce circuit fidelity as a comprehensive metric that captures the effects of SWAP and circuit depth overheads. Leveraging a novel approach based on the SABRE algorithm, we achieve up to $84\%$ higher average circuit fidelity for large devices within the NISQ range, compared to previously existing methods. Additionally, our results highlight that the optimal routing choice critically depends on the qubit count and the hardware characteristics, including gate fidelities and coherence times.

Graph Reinforcement Learning for Calibration-Aware Quantum Circuit Routing
A calibration-aware graph RL router achieves pooled mean fidelity of 0.727 on nine MQT Bench circuits across three IBM calibration snapshots, outperforming SABRE-best20 (0.440) and target-aware SABRE (0.481).

Position: Quantum Program Generation Must Prioritize Validity Over Probabilistic Scaling
The paper argues that probabilistic scaling alone cannot fix the validity gap in quantum circuit generation, so quantum code assistants must build verification into generation rather than filter outputs after the fact.

A Cost-Effective Quantum Boolean-Phase SWAP Gate with Only Two CNOT Gates
A two-CNOT swap-like gate is introduced whose transpiled version has lower gate count and depth than the standard three-CNOT SWAP, at the cost of user-selected phase distortions.
