Shortcuts to adiabaticity: theoretical framework, relations between different methods, and versatile approximations
Takuya Hatomura
Shortcuts to adiabaticity guide given systems to final destinations of adiabatic control via fast tracks. Various methods were proposed as varieties of shortcuts to adiabaticity. B…

The first-order Trotter decomposition in the dynamical-invariant basis
Takuya Hatomura
The Trotter decomposition is a basic approach to Hamiltonian simulation (digital quantum simulation). The first-order Trotter decomposition is the simplest one, whose deviations fr…

Scaling of errors in digitized counterdiabatic driving
Takuya Hatomura
We study errors caused by digitization of shortcuts to adiabaticity by counterdiabatic driving. We find possibility of error scaling with the number of time s…
