Quantum computers are poised to grant an advantage over classical computers for some specific problems. These applications will require fully fault-tolerant quantum computers in order to produce significant results. However, due to the overhead of gates and qubits required by quantum error correction, fault-tolerant computation is out of scope for current devices. This necessitates the development of lightweight yet effective strategies to handle errors in noisy quantum devices. We investigate a [[2m,2m−2,2]] error-detection code based on the ‘Iceberg code’ by applying it to realistic quantum simulations of the Schwinger model. Using an accurate noise model for the two-qubit entangling gate based on the upcoming trapped ion architecture of QUDORA, we simulate the dynamics of the particle number density on a noisy emulator. We demonstrate that the Iceberg code is able to substantially reduce the errors in this simulation, if correctly tuned. To that end, we propose a workflow to optimize the Iceberg code by selecting an optimal number of stabilizer measurements for a given problem. These results show that noisy intermediate-scale quantum computing can extensively be improved by carefully choosing low-overhead error-handling methods.
