At PsiQuantum we are developing and testing prototype modules which will scale into a datacenter-sized, fault-tolerant quantum computer. Modules, or subsystems, of this computer are designed to generate entangled states of photons that, when scaled up and networked together, collectively enable quantum error correction and quantum algorithms. The Quantum Systems Validation team is developing and maintaining a set of physical models to represent, characterize, and analyze the performance of our quantum modules. The Software Engineer, Validation Models will be responsible for building and maintaining software infrastructure that enables the team to capture and analyze system performance data. The successful candidate will work closely with validation engineers to create tools that manage data, create abstractions for system hardware, and interface those to physical modelling tools.
