Overcoming the entanglement barrier with sampled tensor networks
Stefano Carignano, Guglielmo Lami, Jacopo De Nardis +1
The rapid growth of entanglement under unitary time evolution is the primary bottleneck for modern tensor-network techniques--such as Matrix Product States (MPS)--when computing ti…
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…
Learning the stabilizer group of a Matrix Product State
Guglielmo Lami, Mario Collura
We present a novel classical algorithm designed to learn the stabilizer group -- namely the group of Pauli strings for which a state is a eigenvector -- of a given Matrix P…
Continuously Monitored Quantum Systems beyond Lindblad Dynamics
Guglielmo Lami, Alessandro Santini, Mario Collura
The dynamics of a quantum system, undergoing unitary evolution and continuous monitoring, can be described in term of quantum trajectories. Although the averaged state fully charac…
Quantum Magic via Perfect Pauli Sampling of Matrix Product States
Guglielmo Lami, Mario Collura
We introduce a novel breakthrough approach to evaluate the nonstabilizerness of an -qubits Matrix Product State (MPS) with bond dimension . In particular, we consider the rec…
