Recent Business Developments

Rigetti Selected to Participate in DARPA’s Quantum Benchmarking Initiative

Rigetti will advance to Stage A, a 6-month performance period focused on the Company’s utility-scale quantum computer concept worth up to $1 million upon completion of program milestones. Rigetti’s proposed concept to design and build a Utility-Scale Quantum Computer (USQC) combines the Company’s proprietary multi-chip architecture with scalable quantum error correction (QEC) codes. Rigetti’s long-time partner and leader in QEC technology, Riverlane, will be collaborating on this project and bringing their expertise to help refine the proposed USQC concept and validate the underlying technology.

Rigetti Granted AFOSR Award to Further Develop Breakthrough Chip Fabrication Technology

Rigetti will lead a $5.48 million consortium to further develop its breakthrough chip fabrication technology, Alternating-Bias Assisted Annealing (ABAA). Rigetti will collaborate with Iowa State University, the Royal Melbourne Institute of Technology, the University of Connecticut, and Lawrence Livermore National Laboratory* to develop a detailed understanding of how ABAA impacts the chip on a microscopic level — which aims to shed light on defects in superconducting qubits and open new avenues for understanding and mitigating them.

*Funded separately though Laboratory for Physical Sciences, University of Maryland

Rigetti Awarded Three Innovate UK Quantum Mission Pilot Awards to Advance Superconducting Quantum Computing

Rigetti will lead a £3.5 million consortium to advance quantum error correction capabilities on superconducting quantum computers. In collaboration with Riverlane and the National Quantum Computing Centre (NQCC) Superconducting Circuits Team, the consortium will conduct ambitious QEC tests that advance state-of-the-art metrics and demonstrate real-time QEC capabilities — a requirement for universal, fault-tolerant quantum computing.

As part of the project, Rigetti will also upgrade its existing NQCC quantum computer. The upgrades will include:

●

Deploying a larger 36-qubit quantum processing unit (QPU), updating from the current 24-qubit QPU

●

Integrating Rigetti’s latest generation control system, enabling improved qubit control and a fully programmable, low-latency interface with Riverlane’s QEC Stack

Rigetti was also awarded two additional Quantum Missions pilot competition projects:

●

Collaboration with SEEQC to integrate its digital chip-based technology with Rigetti’s 9-qubit Novera™ QPU hosted at the NQCC with the goal of identifying and understanding the key system components needed for scalable QEC.

●

Collaboration with TreQ, Qruise, Q-CTRL, and Oxford Ionics aims to create an open-architecture quantum computing testbed and deliver an open specification for quantum workflows, creating a common interface between quantum software and hardware.

Rigetti Closes Investment by Quanta Computer

On April 29, 2025, Rigetti closed its previously announced investment by Quanta Computer Inc. related to our strategic collaboration agreement. In connection with the closing, Quanta purchased approximately $35 million of shares of Rigetti common stock at approximately $11.59 per share.

Recent Technical Updates

Controlling a Superconducting Qubit Using Optical Signals

Rigetti's joint paper with Harvard University, Massachusetts Institute of Technology, and University of Chicago, “Coherent control of a superconducting qubit using light,” has been published in Nature Physics.

Fault-tolerant quantum computing will likely require 10,000 to a million physical qubits. Scaling these systems is challenging because they require bulky microwave components with high thermal loads that can quickly overwhelm the cooling power of a dilution refrigerator. Optical signals have a considerably smaller footprint and negligible thermal conductivity.

The team successfully demonstrated the integration of a hybrid microwave-optical quantum transducer with a Rigetti-fabricated superconducting qubit. This hybrid set-up enables optical control of the qubit, removing the need for coax lines and provides a promising approach to scaling to higher qubit count systems.

New Quantum Algorithm Boosts Classical Optimizers

Rigetti leveraged its new quantum optimization algorithm, quantum preconditioning, to address a power energy grid problem. Using a public dataset representing South Carolina’s energy grid, the problem was to compute the maximum power exchange section, a metric that informs on the health and the power delivery capability of the energy network. Using Rigetti’s 84-qubit Ankaa-3 system, quantum preconditioning was used to boost best-in-class classical optimizers. A relative advantage against the classical baseline was achieved along with a high solution accuracy, highlighting the potential for quantum preconditioning to achieve quantum utility for solving practical optimization problems.

Conference Call and Webcast
Rigetti will host a conference call later today, May 12, 2025, at 5:00 pm ET, or 2:00 pm PT, to discuss its first quarter 2025 financial results.
