On the stability to noise of fermion-to-qubit mappings
Guillermo González-GarcÃa, Filippo Maria Gambetta, Raul A. Santos
Quantum simulations before fault tolerance suffer from the intrinsic noise present in quantum computers. In this regime, extracting meaningful results greatly benefits from stabili…

Dynamical complexity of non-Gaussian many-body systems with dissipation
Guillermo González-GarcÃa, Alexey V. Gorshkov, J. Ignacio Cirac +1
We characterize the dynamical state of many-body bosonic and fermionic many-body models with inter-site Gaussian couplings, on-site non-Gaussian interactions and local dissipation…

Pauli path simulations of noisy quantum circuits beyond average case
Guillermo González-GarcÃa, J. Ignacio Cirac, Rahul Trivedi
For random quantum circuits on qubits of depth with depolarizing noise, the task of sampling from the output state can be efficiently performed classically using a…
