In addition to decoherence, coherent errors in the quantum gate operations form a substantial error source in current quantum computing processors. These errors are typically only addressed with the calibration of control parameters. Fully compensating composite pulse sequences inspired by the NMR field have been identified as a possible measure to mitigate these errors in superconducting qubits. Here, the performance of two sequences, SCROFULOUS and BB1, applicable to an arbitrary single-qubit gate, is simulated and run on a 5-qubit IQM device. Both are able to correct for pulse amplitude errors on a wide range, but perform worse in terms of the accumulation of errors during multiple gates. It is concluded that the sequences do not offer benefits over standard calibration procedures since the native gate is the most accurate in the studied system.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2023-04-13T05:59:33Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-04-13T05:59:33Z (GMT).
