The Story

Timeline.

2013

Founded by IBM veteran Chad Rigetti in Berkeley.

2017

Opens Fab-1, the first dedicated quantum chip fab in the U.S.

2020

Launches Quantum Cloud Services with 32-qubit Aspen systems.

2022

Goes public on Nasdaq via SPAC.

2024

What makes them different

Key Facts

  • One of the only quantum companies to own its full chip fabrication line.
  • Uses 3D chip stacking to keep control wiring off the qubit plane.
  • Focus on 'quantum advantage in a hybrid loop' with classical HPC.
  • Deep partnerships with U.S., U.K. and Australian defense research.

Real-world pilots

Quantum Uses Today

  • Government research contracts including DARPA and NASA.
  • Hybrid quantum-classical machine learning experiments.
  • Quantum-classical benchmarking suites for the industry.

If they succeed

Potential Applications

  • Quantum simulation of correlated electron systems.
  • Optimization for defense logistics and cybersecurity.
  • On-premise quantum accelerators for HPC data centers.
