IonQ (NYSE: IONQ), a leader in quantum computing, today published results from its new barium-based quantum computer showing its superior state detection fidelity. The results reflect a 13x reduction in state preparation and measurement (SPAM) errors, a metric core to producing accurate and reliable quantum computers. On a per-qubit basis, IonQ has reduced these errors from 50 errors per 10,000 computations down to only 4 errors per 10,000 computations. In other words, IonQ’s barium qubits have brought the company from a 99.5% state detection fidelity up to an industry-leading 99.96%.
