Variational ground-state quantum adiabatic theorem
Bojan Žunkovič, Pietro Torta, Giovanni Pecci +2
We present a variational quantum adiabatic theorem, which states that, under certain assumptions, the adiabatic dynamics projected onto a variational manifold follow the instantane…
Beyond Quantum Annealing: Optimal control solutions to MaxCut problems
Giovanni Pecci, Ruiyi Wang, Pietro Torta +2
Quantum Annealing (QA) relies on mixing two Hamiltonian terms, a simple driver and a complex problem Hamiltonian, in a linear combination. The time-dependent schedule for this mixi…
Quantum Annealing for Neural Network optimization problems: a new approach via Tensor Network simulations
Guglielmo Lami, Pietro Torta, Giuseppe E. Santoro +1
Quantum Annealing (QA) is one of the most promising frameworks for quantum optimization. Here, we focus on the problem of minimizing complex classical cost functions associated wit…
Avoiding barren plateaus via transferability of smooth solutions in Hamiltonian Variational Ansatz
Antonio Anna Mele, Glen Bigan Mbeng, Giuseppe Ernesto Santoro +2
A large ongoing research effort focuses on Variational Quantum Algorithms (VQAs), representing leading candidates to achieve computational speed-ups on current quantum devices. The…
Quantum Approximate Optimization Algorithm applied to the binary perceptron
Pietro Torta, Glen B. Mbeng, Carlo Baldassi +2
We apply digitized Quantum Annealing (QA) and Quantum Approximate Optimization Algorithm (QAOA) to a paradigmatic task of supervised learning in artificial neural networks: the opt…
Two-dimensional lattice gauge theory on a near-term quantum simulator: variational quantum optimization, confinement, and topological order
Luca Lumia, Pietro Torta, Glen B. Mbeng +4
We propose an implementation of a two-dimensional lattice gauge theory model on a shallow quantum circuit, involving a number of single and two-qubits gates comparab…
