PsiQuantum

PsiQuantum is building a silicon photonic quantum computer. While other approaches start with a quantum process and try to make it scale, PsiQuantum started with a scalable process and made it quantum, relying on the cost-effective processes of the semiconductor and silicon photonic industries based in Silicon Valley. Great progress has been made in building a million qubit general purpose machine and software stack. The company is on a path to deliver quantum computing as a service in just a few short years. It could revolutionize industries such as energy, materials science, personalized medicine, finance and security.
