Nonadiabatic Self-Healing of Trotter Errors in Digitized Counterdiabatic Dynamics
Mara Vizzuso, Gianluca Passarelli, Giovanni Cantele +3
Trotter errors in digitized quantum dynamics arise from approximating time-ordered evolution under noncommuting Hamiltonian terms with a product formula. In the adiabatic regime, s…
Physics-Informed Neural Networks for Maximizing Quantum Fisher Information in Time-Dependent Many-Body Systems
Antonio Ferrer-Sánchez, Yolanda Vives-Gilabert, Yue Ban +2
Quantum Fisher Information (QFI) sets the ultimate precision limit for parameter estimation and is therefore a central quantity in quantum metrology. In time-dependent many-body sy…
Classical counterparts of shortcuts to adiabaticity in nonlinear dissipative Lagrangian systems
Jincheng Shi, Yicheng Pan, Yue Ban +1
Shortcuts to adiabaticity (STA) were first developed in quantum dynamics to realize rapid transformations with suppressed residual excitations. Here we show how the same idea can b…
Optimizing thermal convection by phase-locking circulation to wall oscillations
YaLin Zhu, Jian-Chao He, Xi Chen
This study numerically investigates two-dimensional Rayleigh-Benard convection subjected to horizontal oscillation of the bottom plate, with Prandtl number Pr=4.3, Rayleigh numbers…
Fast compression of pure-quartic solitons in nonlinear optical fibers via shortcuts to adiabaticity
Chengyu Han, Qian Kong, Ming Shen +1
Pure-quartic solitons (PQSs) supported by negative fourth-order dispersion have recently attracted considerable interest. In this work, we study both adiabatic and nonadiabatic com…
Quantum Transport Protected by Acceleration From Nonadiabaticity and Dissipation
Arnab Chakrabarti, Biswarup Ash, Igor Mazets +2
We put forth a hitherto unexplored control strategy that enables high-fidelity fast transport of an unstable quantum wavepacket even in the presence of bath-induced dissipation. Th…
