Constant-Depth Multi-Product Formula for Trotter Error Mitigation in Near-Term Digital Quantum Simulation
Chan Bin Bark, Sangjin Lee, Kwang Jun Ahn +3
Digital quantum simulation of many-body dynamics faces a tension between algorithmic Trotter error and physical noise that accumulates with circuit depth. Typical higher-order prod…
Mitigating Trotter Errors via Post-Processed Symmetry Restoration
Sangjin Lee, Sangkook Choi
Quantum simulation is a powerful tool for exploring complex quantum many-body systems such as condensed matter physics and gauge theories. Trotterization, which approximates the id…
Generation of immersed Lagrangians by cocores
Wonbo Jeong, Dogancan Karabas, Sangjin Lee
We extend the generation theorem of Chantraine--Dimitroglou Rizell--Ghiggini--Golovko to exact Lagrangian immersions in Weinstein manifolds. We prove that an exact Lagrangian immer…
Proper modules over Ginzburg dg algebras and compact Fukaya categories of plumbings
Wonbo Jeong, Dogancan Karabas, Sangjin Lee
We study Ginzburg dg algebras which appear at the intersection of representation theory and symplectic topology. First, we provide a collection of proper modules that generates all…
qSHIFT: An Adaptive Sampling Protocol for Higher-Order Quantum Simulation
Sangjin Lee, Sangkook Choi
Quantum simulation is a cornerstone application for quantum computing, yet standard methods face a trade-off between circuit depth and accuracy: Trotterization depth scales with th…
The wrapped Fukaya category of plumbings
Dogancan Karabas, Sangjin Lee
Plumbing spaces have drawn significant attention among symplectic topologists due to their natural occurrence as examples of Weinstein manifolds. In our paper, we provide a general…
