Summary

NP-aided shadow tomography linked several proposed quantum pseudorandom constructions back to one-way functions or NP hardness.

The paper develops learning tools for computable pure states and queried unitaries, then applies them to candidate pseudorandom-state and pseudorandom-unitary architectures. Its conclusions are theoretical constraints on classes of constructions, intended to guide future Microcrypt designs.
