Quantum-Geometric Length Scale for Long-distance Squeezing in Bosonic Bogoliubov Systems
Sonu Verma, Sangmo Cheon, Myung-Joong Hwang +1
Multimode squeezing is a key resource for continuous-variable quantum technologies, but its spatial range in bosonic lattices is usually tied to dispersive propagation. Here we sho…

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…
