The surface code is a leading quantum error correction candidate for fault-tolerant quantum computing. Within this framework, Pauli-based computation eliminates Clifford gates at the cost of higher-weight multi-qubit operators that require large ancilla patches. The dominant bottleneck for scaling such systems across d...

Quantum error-correcting decoders provide both corrections and confidence estimates for the logical-error risk of individual measurement records. Such confidence can guide postselection, but it depends on the accuracy of the decoder noise model. When the physical device drifts away from that model, confidence measures...

Hybrid quantum-classical application performance is increasingly limited by classical control, host-to-QPU communication, and scheduling rather than quantum execution. Existing simulators and runtime interfaces analyze individual kernels but fail to address system-topology questions, such as controller bottlenecks, dim...
