Good afternoon and thank you for participating in Rigetti's earnings conference call covering the fourth quarter and year ended December 31st, 2023. Joining me today is Jeff Bertelsen our CFO who will review our results in some detail following my overview. Our CTO, David Rivas is also here to participate in the Q&A session. We will be pleased to answer your questions at the conclusion of our remarks. We would like to point out that this call and Rigetti's Q4 and year ended December 31st, 2023 press release contain forward-looking statements regarding current expectations, objectives, and underlying assumptions regarding our outlook and future operating results. These forward-looking statements are subject to a number of risks and uncertainties that could cause actual results to differ materially from those described and are discussed in more detail in our annual report on Form 10-K for the year ended December 31st, 2023 and other documents filed by the company from time to time with the Securities and Exchange Commission. These filings identify and address important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. We urge you to review these discussions of risk factors. Turning now to recent events, I am pleased to report on a number of new developments. In February 2024, we were awarded a Small Business Research Initiative grant from Innovate UK and funded by the National Quantum Computing Center to develop and deploy a 24-qubit quantum computer based on our Ankaa class architecture. The proposed system is planned to be deployed at NQCC's Harwell Campus, which is expected to open later this year and will serve as NQCC's landmark facility to support quantum computing research in the UK. Since deploying our first UK-based quantum computer in 2022, we have had the privilege of collaborating with the UK's talented quantum computing research community. We believe building a system at the NQCC could enable even more innovative discoveries to deepen our understanding of how to improve superconducting quantum computers with the goal of solving practical problems currently intractable by classical resources alone. In December 2023, we launched the Novera quantum processing unit, our first commercially available QPU. Novera has 9-qubit and is based on our Ankaa class chip architecture. We have completed two Novera QPU sales, both to leading national labs. The first sale was to the Superconducting Quantum Materials and Systems Center, led by Fermilab in the second quarter of 2023. In the third quarter of 2023, we delivered our second Novera QPU to the Air Force Research Lab Information Directorate as part of our Indefinite Delivery Indefinite Quantity contract. The IDIQ contract enables AFRL to harvest Rigetti's fabrication capabilities for quantum networking hardware research and development. We are continuing our efforts to develop quantum computing solutions for financial institutions. We were recently awarded an Innovate UK grant with the aim to develop quantum machine learning techniques to enable financial institutions to more effectively process, interpret, and make decisions with complex data streams. Joining Rigetti in this project is Amazon Web Services, Imperial College London, and Standard Chartered. We were recently awarded Phase 2 of the DARPA program, which aims to develop a resource estimation framework to provide insight into the requirements of a superconducting quantum computing system necessary for solving large-scale complex problems. The goal of Phase 2 is to refine and optimize the estimates for selected utility-scale problems, delivering new upper bounds on these requirements. The University of Technology Sydney, Aalto University, and the University of Southern California will continue to be project partners in Phase 2. We are partnering with Riverlane and Oak Ridge National Laboratory to work to improve high performance computing and quantum integration. To develop the integration of quantum computers into high performance computing environments, the project partners plan to build a first-ever benchmarking suite for measuring the performance of a joint HPC plus quantum system to be run on ORNL's Summit supercomputer. For the quantum components, researchers plan to use simulated hardware based on key elements of Riverlane's quantum error correction stack and real remote hardware located at our headquarters in California. And now a few comments regarding our technology roadmap. Following the internal development of 84-qubit Ankaa-1 system in March 2023, our 84-qubit Ankaa-2 system was made publicly available in December 2023. The 84-qubit Ankaa-2 system is our highest qubit count QPU available to the public. In addition to a new chip architecture that features a square lattice and tunable couplers, Ankaa-2 includes a new chip fabrication process, new printed circuit board technology, and electronics improvements. Combined, this improvements contributed to Ankaa-2 achieving a 98% median 2-qubit gate fidelity, a 2.5x increase in error performance compared to our prior QPUs. We plan to develop and deploy our anticipated 84-qubit Ankaa-3 system with the goal of achieving 99% median 2-qubit gate fidelity by the end of 2024. Thereafter, it's our plan to develop the 336-qubit Lyra system. We are confident in our ability to build better performing QPUs as evidenced by our impressive Ankaa-2 performance. We believe we have laid the groundwork for building scalable, high performing QPUs with our proven modular chip architecture and innovative Ankaa chip design that resulted in a 98% median 2-qubit gate fidelity. We are excited for the anticipated development and deployment of our Ankaa-3 system which we believe will demonstrate the excellence and ingenuity of our R&D teams. We believe our leadership and expertise in full-stack quantum systems, paired with our strong collaborations with researchers around the world across academia, industry and government, puts us in a unique position to tackle the challenges of building a quantum computer capable of addressing real-world problems. With Rigetti QPUs now in two research labs internationally, we are even more optimistic that practical quantum computing is in reach. Jeff will now make a few remarks regarding our recent financial performance.
