Refik Mansuroglu

Refik read physics at the Friedrich-Alexander-University of Erlangen-Nürnberg and joined Prof. Hartmann’s

research group in fall 2020. Refik is interested in developing NISQ algorithms for digital quantum computing. In particular, he has been studying the exploitation of translational symmetries for Hamiltonian Simulation by optimizing Trotter-Suzuki decompositions with variational algorithms on NISQ devices. By doing the optimization in classical pre-processing, the optimization and sampling effort on the quantum machine can be significantly reduced.

Furthermore, he is investigating cooling-assisted algorithms for ground state preparation. While digital cooling algorithms have already been proposed, he is looking for applications of cooling to improve error mitigation as well as known ground state preparation algorithms such as adiabatic algorithms and QAOA.

Also, coming from the chair for Loop Quantum Gravity where he studied the interaction of spin degrees of freedom with spin network states, the “atoms” of spacetime, during his master project, he strives to better understand the appearance of fault tolerant structures in quantum gravitational states. Building upon holographic codes, such as the HaPPY code, searching for codes that respect the gauge symmetries of gravity might yield a natural information loss protection.
