IonQ (NYSE: IONQ) has announced that its IonQ Tempo system, a 100-qubit trapped-ion quantum computer, has achieved an algorithmic qubit score of #AQ 64. This milestone was achieved three months ahead of schedule, with #AQ serving as an application-based benchmark that aggregates performance across six quantum algorithms.
The company states that with each increment in #AQ value, the useful computational space for running quantum algorithms doubles. A system with #AQ 64 is capable of considering more than 2^64 possibilities and is claimed to have a computational space that is 36 quadrillion times larger than IBM’s current publicly available quantum systems. The company also highlighted new benchmark comparisons, where its Aria and Forte systems showed a 35% improvement in solution quality on an optimization algorithm (QAOA), a 74% improvement on a foundation algorithm (QFT), and a 182% improvement on a search algorithm (FAA) over competing systems.
With #AQ 64, the IonQ Tempo system is expected to be capable of commercial advantage for certain applications, including energy grid distribution improvements, computational drug discovery, and supply chain optimization. The company plans to report additional metrics beyond physical qubits, such as logical qubits, logical error rates, and a collection of industry-relevant application benchmarks. This news follows a series of strategic announcements by IonQ, including its accelerated technology roadmap and several acquisitions.
