Abstract

TEMPO (Time-dependent Evolution of Multiple Pulse Operations) offers accessible and efficient simulations of pulse sequences in Python, using the suite of master equation solvers available in the Quantum Toolbox in Python (QuTiP). It enables straightforward definition of pulse sequence structures, including any underlying time-dependent Hamiltonians and pulse timing information, and faster simulations of pulse sequence dynamics (compared to naive implementations using QuTiP) while remaining compatible with the existing collection of QuTiP subpackages. Given the ubiquitous use of pulse sequences throughout quantum information/computing sciences, magnetic resonance studies, and quantum metrology, this work has immediate relevance to a wide array of research applications.
