Adaptive time Compressed QITE (ACQ) and its geometrical interpretation
ACQ combines adaptive time steps and circuit compression for QITE, achieving comparable fidelity to standard QITE on the Transverse Field Ising Model with fewer optimizations and fixed circuit depth, motivated by geodesic properties in CP^N.
