- Abstract: Programming analog quantum processing units (QPUs), such as those produced by Pasqal, can be achieved using specialized low-level pulse libraries like Pulser. However, few currently offer the possibility to optimize pulse sequence parameters. In this paper, we introduce PulserDiff, a user-friendly and open-source Pulser extension designed to optimize pulse sequences over a well-defined set of control parameters that drive the quantum computation. We demonstrate its usefulness through several case studies involving analog configurations that emulate digital gates and state preparation. PulserDiff produces hardware-compatible pulses with remarkably high fidelities, showcasing its potential for advancing analog quantum computing applications.
