Shortcuts to Adiabaticity for Quantum Computation and Simula

Adiabatic processes are at the core of countless experiments, and they find numerous applications in quantum simulations and quantum computing. STAQS will develop a comprehensive set of non-adiabatic building blocks that replace the adiabatic state preparation by non-adiabatic processes using shortcuts to adiabaticity (STA). This fundamentally new paradigm allows one to detach from the adiabatic limit, which currently hinders practical applications, by introducing additional unitary quantum operation s to the system. In a joint effort of leading experimental and theory groups, the project will demonstrate the first two-body STA experiment with a scalable architecture, the first STA experiment with a non-scale-invariant system, a novel theoretical framework for STA of statistical ensembles and a novel tensor network framework for STA. We expect a broad impact ranging from fundamental science experiments to applications in commercial quantum devices. Regarding the latter, the general demand for scalable and technologically feasible quantum optimization tools emphasized the disruptive character of STAQS.
