A natural alternative is quantum Hamiltonian simulations of highly complex many body quantum evolutions. In a recent work with Zhou, we proved that very simple families of Hamiltonians, even in 1D, are capable of performing universal Hamiltonian simulations. However, as I will explain in the talk, there are inherent difficulties in viewing existing experiments of Hamiltonian simulations as evidence for scalable quantum advantage. So far no (conjectured to be) computationally hard problem was identified and convincingly verified to be solved efficiently by quantum Hamiltonian simulations.
While evidence for scalable quantum advantage is still wanting, initial finite size quantum advantages might be much closer. In the last part of my talk I will describe recent demonstrations on IBM and IONQ quantum devices, performed by my company Qedma's team using Qedma's error mitigation software. These experiments demonstrate unbiased quantum Hamiltonian simulations of unprecedented volumes, suggesting that with devices of 99.9% two-qubit gate fidelities, initial quantum advantages of Hamiltonian simulations can already be demonstrated.

This specialized seminar is designed for researchers working in the same field as Dorit Aharonov.
