On Tuesday at #IQOQI Tobias Olsacher explained to me how to verify #HamiltonianSimulation. The paper https://arxiv.org/abs/2203.15846 is full of tricks and ideas, going towards a tutorial reviewing what you can do if you have access to decent measurements and enough coherence to make the characterization of a #QuantumDevice challenging.
The Hamiltonian learning involving an energy constraint is extremely #neat 💯 as an idea but apparently is sensitive to non-unitarity. A generalization is possible to do without an exact energy constraint and learn a parametrized Liouvillian but haih do we always need to need so many measurements? #quantum 🥲
