TL;DR: Several quantum simulations of chemistry with up to one dozen qubits are performed, including modeling the isomerization mechanism of diazene, and error-mitigation strategies based on N-representability that dramatically improve the effective fidelity of the experiments are demonstrated.

Learning to learn with quantum neural networks via classical neural networks
Guillaume Verdon,Michael Broughton,Jarrod R. McClean,Kevin Sung,Ryan Babbush,Zhang Jiang,Hartmut Neven,Masoud Mohseni +7 more
TL;DR: This work trains classical recurrent neural networks to assist in the quantum learning process, also know as meta-learning, to rapidly find approximate optima in the parameter landscape for several classes of quantum variational algorithms.

Quantum algorithms to simulate many-body physics of correlated fermions
TL;DR: In this article, the authors develop quantum algorithms that run on two-dimensional qubit lattices with nearest-neighbor interactions, to simulate strongly correlated fermions, avoiding the parity problem in mapping fermionic operators to qubit operators, with hardly any overhead.
