Global Non-Identifiability of Fubini-Study Geometry from Complete One-Period Endpoint Data

arXiv:2608.10051v1 Announce Type: new Abstract: We establish a global, worst-case non-identifiability theorem for periodically driven finite-dimensional quantum systems. On the unrestricted smooth periodic Hamiltonian class, we show that the period-averaged Fubini-Study metric component of a fixed
