Programming analog quantum processing units (QPUs) can be achieved using specialized low-level pulse libraries like Pulser. However, few currently offer the possibility to optimize pulse sequence parameters.
In this contribution to the EQUALITY project, PASQAL researchers 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. The authors 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.
