At Rigetti, we believe that quantum computers have the power
to solve previously unsolvable problems and address fundamental
challenges in medicine, energy, business, and science. 


Predicting the properties of complex molecules and materials will help us design more effective medicines, energy technologies and more resilient crops. 

Machine Learning

Training advanced AI on quantum computers will advance computer vision, pattern recognition, voice recognition and machine translation.


Solving complex optimizations such as ‘job shop’ scheduling and traveling salesperson problems will drive critical efficiencies in businesses, military and public sector logistics, scheduling, shipping and resource allocation.
