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…
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…
Optimal Control for Open Quantum System in Circuit Quantum Electrodynamics
Mo Zhou, F. A. Cárdenas-López, Sugny Dominique +1
We propose a quantum optimal control framework based on the Pontryagin Maximum Principle to design energy- and time-efficient pulses for open quantum systems. By formulating the La…
