Now published in PRX Quantum:
A robust control framework based on optimized pulse sequences enables faithful realization of arbitrary local Hamiltonians, scaling efficiently to hundreds of qubits.
Together with @markusheinrich.bsky.social and Martin Kliesch.

Check out our updated preprint for many more interesting results regarding the efficient and robust engineering of Hamiltonians.
Thank you @markusheinrich.bsky.social and Martin Kliesch for the good & fun collaboration!
We provide numerical simulations to highlight the performance. Given an Ising Hamiltonian as system Hamiltonian we are able to implement general Heisenberg Hamiltonians with a fidelity larger than 99.9%. This high fidelity is even achieved while various errors are present.
Our method only requires the evolution under an arbitrary system Hamiltonian given by the quantum platform and simple single-qubit pulses. With that we implement the evolution under a desired target Hamiltonian which is only limited by the locality of the system Hamiltonian.
We provide an efficient method to engineer arbitrary many-body Hamiltonians also robust against various dominant errors.
I will present these results next Wednesday at #QCTIP2025.

The doors to #QCTiP2025 are about to open! From next Wednesday to Friday, Berlin will host the largest international conference on quantum computing theory in practice—at the beautiful and historic Harnack House, where Schrödinger, Einstein, and Planck once came and went.
