Semantic Steering for Controllable Generation: Tuning-Free Concept Erasure in Multimodal Diffusion Transformers
Qiao Li, Xiaomeng Fu, Yuanshu Zhao +3
Multimodal Diffusion Transformers (MM-DiTs) have demonstrated remarkable text-to-image generation performance, surpassing traditional U-Net-based diffusion models. Nevertheless, th…
Provable Quantum Speedups for Reaction-Rate Estimation in High-Dimensional Fokker-Planck Dynamics
Tyler Kharazi, Ahmad M. Alkadri, Kranthi K. Mandadapu +1
The Fokker-Planck equation models rare events across sciences, but blue{direct solution of the PDE is intractable for classical computers due to } its high-dimensional nature. Clas…
Towards Heisenberg Scaling: Measurement-Efficient Non-Orthogonal Quantum Eigensolver
Hang Ren, Yipei Zhang, Thilo Scharnhorst +1
The Non-Orthogonal Quantum Eigensolver (NOQE) provides an accurate framework for electronic-structure calculations, but the estimation of its Hamiltonian and overlap matrix element…
Exponential quantum speedups for near-term molecular electronic structure methods
Oskar Leimkuhler, K. Birgitta Whaley
We prove classical simulation hardness, under the generalized conjecture, for quantum circuit families with applications in near-term chemical ground st…
A quantum eigenvalue solver based on tensor networks
Oskar Leimkuhler, K. Birgitta Whaley
Electronic ground states are of central importance in chemical simulations, but have remained beyond the reach of efficient classical algorithms except in cases of weak electron co…
Optimal sensing on an asymmetric exceptional surface
Robert L. Cook, Liwen Ko, K. Birgitta Whaley
We study the connection between exceptional points (EPs) and optimal parameter estimation, in a simple system consisting of two counter-propagating traveling wave modes in a micror…
