We recently announced a new approach to vastly increasing the efficiency of running quantum algorithms. We call it the Active Volume Architecture. The key insight is that if you have access to certain hardware capabilities then you can obtain remarkable reductions in the running costs of commercially useful quantum algorithms (for example, reducing running costs by around 50x for factoring algorithms).

Fusion based quantum computation (FBQC) is designed to implement fault-tolerant quantum computing with the photonic hardware used at PsiQuantum. By efficiently using native operations this approach can be more robust against errors, allowing it to tolerate approximately five times more photon loss compared to previous photonic architectures. Importantly, the approach is modular, which means it can be scaled across multiple machines without a significant loss of performance.
