02 / Current work
DLR Quantum Computing Initiative
Project leadership and hardware-near research
ALQU
Algorithms for quantum computer development through hardware–software co-design.
ALQU addresses a central challenge of current NISQ systems: quantum algorithms must account for the properties, limitations, and errors of real hardware.
The work focuses on error-aware and hardware-specific compilation, bringing algorithm design and physical architectures into closer alignment.
