Noise robustness of problem-to-simulator mappings for quantum many-body physics
Rahul Trivedi, J. Ignacio Cirac
Simulating quantum dynamics on digital or analog quantum simulators often requires ``problem-to-simulator" mappings such as trotterization, floquet-magnus expansion or perturbative…
Optimizing digital quantum simulation of open quantum lattice models
Xie-Hang Yu, Hongchao Li, J. Ignacio Cirac +1
Many-body systems arising in condensed matter physics and quantum optics inevitably couple to the environment and need to be modelled as open quantum systems. While near-optimal al…
Quantum Circuits for Matrix-Product Unitaries
Georgios Styliaris, Rahul Trivedi, J. Ignacio Cirac
Matrix-product unitaries (MPUs) are many-body unitary operators that, as a consequence of their tensor-network structure, preserve the entanglement area law in 1D systems. However,…
Exact Many-body Quantum Dynamics in One-Dimensional Baths via Collective Spins
Joseph T. Lee, Silvia Cardenas-Lopez, Stuart J. Masson +2
Computing the exact dynamics of many-body quantum systems becomes intractable as system size grows. Here, we present a symmetry-based method that provides an exponential reduction…
Dynamical complexity of non-Gaussian many-body systems with dissipation
Guillermo González-García, 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…
