Preliminary Analysis of the Impact of External Parameters on the Performance of a 2-Qubit NMR Desktop Quantum Computer

In recent years, quantum computing has become increasingly relevant across many application domains, partly due to the growing availability of the latest generation of desktop quantum computers. However, since these systems are relatively less expensive and lack sophisticated conditioning and isolation mechanisms, they may be prone to computational errors or deviations from expected results caused by various factors. For this reason, developing methods to minimize or correct quantum errors, both in terms of spurious outcomes and quantum decoherence, is essential, as these effects may arise from the influence of external parameters within the computer's operating environment. Nevertheless, as this is an emerging paradigm, standardized procedures for sensitivity analysis and device characterization are still needed. This work represents an initial step toward establishing characterization procedures aimed at estimating the repeatability of results produced by a 2-qubit Nuclear Magnetic Resonance (NMR)-based desktop quantum computer under controlled external parameters.
