Quantum Advantage: Our Central Focus Quantum Focus: Quantum Machine Learning Advantage GTM Strategic Government & finance partners Business Model TM QCS Direct, Public clouds, & DoE Cloud Delivery System Architecture An industry leader in speed, based 1 Hybrid on CLOPS Processor Architecture Unlocks performance at scale Multi-chip Strategy Fab-1 facility Pure-play & full-stack Modality Scalable, engineerable approach Superconducting 1 Circuit layer operations per second, or CLOPS, characterizes quantum processing speeds inclusive of gate speeds, reprogrammability, and co-processing capabilities, among other factors. CLOPS was initially developed by IBM in October 2021. CLOPS is calculated as M × K × S × D / time taken where: M = number of templates = 100; K = number of parameter updates = 10; S = number of shots = 100; and D = number of QV layers = log2 QV. To Rigetti’s knowledge, CLOPS as a speed test has not been investigated or verified by any independent third party. In addition, while Rigetti applied the above formula in testing the speed of Aspen-M-2 and Aspen-11, there is no guarantee that Rigetti applied the test in the same way as IBM and, as a result, any variability in the application of the test as between Rigetti, IBM or others in the industry that may apply CLOPS in the future could render CLOPS scores incomparable and actual relative performance may materially differ from reported results. Other than IBM, others in the industry have not announced CLOPS as a speed test. As a result, the speed of other competitors as measured by CLOPS is not currently known. In addition, the solution accuracy provided by quantum computers is another key factor, and a quantum computer that may be slower may be preferable to users if it provides a more accurate answer for certain applications. Moreover, the relative leads reflected by speed tests Copyright Rigetti Computing 2023 such as CLOPS can change as new generations of quantum computers are introduced by industry participants and, consequently, any advantages cannot 11be considered permanent and can be expected to change from time to time. Current CLOPS tests may not be indicative of the results of future tests.
