“We believe the time for quantum computing has arrived,” said Chad Rigetti, founder and Chief Executive Officer of Rigetti. “Customer demand is increasing as Rigetti quantum computers begin to address high-impact computational problems.

“Consistent with our mission to build the world’s most powerful computers to help solve humanity’s most important and pressing problems, Rigetti achieved many critical milestones in 2021. We introduced the 80-qubit Aspen-M system, the world’s first multi-chip quantum processor, expanded our customer and partner footprint, and delivered substantial year-over-year revenue growth,” continued Rigetti. “We look forward to continued momentum as we expect customers to leverage the increasing speed and scale of Rigetti hardware and quantum solutions in their pursuits to solve important problems that lie beyond the capabilities of today’s classical computers.”

Rigetti is fully vertically integrated, from chip design and production to cloud delivery. Rigetti’s primary business model is Quantum Computing as a Service (“QCaaS”). In 2021, Rigetti introduced the world’s first scalable multi-chip quantum processor, which Rigetti believes is a key advancement in quantum processor scalability. Industry researchers estimate fully fault tolerant quantum computers could ultimately produce up to $850 billion in annual value creation for end-users and technology companies. Rigetti believes its scalable chip technology has the potential to help unlock this transformative opportunity going forward.
