  abstract     = {{The Fubini-Study metric is a central element of information geometry. We explore the role played by information geometry for determining the circuit complexity of Virasoro circuits and their deformations. To this effect, we study unitary quantum circuits generated by the Virasoro algebra and Fourier modes of a primary operator. Such primary-deformed Virasoro circuits can be realized in two-dimensional conformal field theories, where they provide models of inhomogeneous global quenches. We consider a cost function induced by the Fubini-Study metric and provide a universal expression for its time-evolution to quadratic order in the primary deformation for general source profiles. For circuits generated by the Virasoro zero mode and a primary, we obtain a non-zero cost only if spatial inhomogeneities are sufficiently large. In this case, we find that the cost saturates when the source becomes time-independent. The exact saturation value is determined by the history of the source profile. As a byproduct, returning to undeformed circuits, we relate the Fubini-Study metric to the Kähler metric on a coadjoint orbit of the Virasoro group.}},
