Now, Frak Wlhelm-MAuch from @Saar_Uni on Quantum Computers in 2018.

@Saar_Uni Frank Wilhem-Mauch: Quantum simulation by Trotter uses many gates, and is currently undoable. Using an hybrid classical-quantum algorithm, the variational eigensolver is much better. #LTQI

@Saar_Uni Frank Wilhelm-Bauch want to use the same approachch in crystalline materials instead of molecules. He is not interested in the ground state, but the the time-ordered 2 points Green-function #LTQI

@Saar_Uni Frank Wilhelm-Mauch: Quantum advantage can be attained from 55 qubits.
This quantum subroutine is useful, but in the long term, we need to go further and need fault tolerance
