Learning efficient decoders for quasi-chaotic quantum scramblers

Lorenzo Leone, Salvatore F. E. Oliviero, Seth Lloyd +1

Scrambling of quantum information is an important feature at the root of randomization and benchmarking protocols, the onset of quantum chaos, and black-hole physics. Unscrambling…

Unscrambling Quantum Information with Clifford decoders

Salvatore F. E. Oliviero, Lorenzo Leone, Seth Lloyd +1

Quantum information scrambling is a unitary process that destroys local correlations and spreads information throughout the system, effectively hiding it in nonlocal degrees of fre…

On the practical usefulness of the Hardware Efficient Ansatz

Lorenzo Leone, Salvatore F. E. Oliviero, Lukasz Cincio +1

Variational Quantum Algorithms (VQAs) and Quantum Machine Learning (QML) models train a parametrized quantum circuit to solve a given learning task. The success of these algorithms…

Retrieving information from a black hole using quantum machine learning

Lorenzo Leone, Salvatore F. E. Oliviero, Stefano Piemontese +2

In a seminal paper[JHEP09(2007)120], Hayden and Preskill showed that information can be retrieved from a black hole that is sufficiently scrambling, assuming that the retriever has…

Magic-state resource theory for the ground state of the transverse-field Ising model

Salvatore F. E. Oliviero, Lorenzo Leone, Alioscia Hamma

Ground states of quantum many-body systems are both entangled and possess a kind of quantum complexity as their preparation requires universal resources that go beyond the Clifford…

Nonstabilizerness determining the hardness of direct fidelity estimation

Lorenzo Leone, Salvatore F. E. Oliviero, Alioscia Hamma

In this work, we show how the resource theory of nonstabilizerness quantifies the hardness of direct fidelity estimation protocols. In particular, the resources needed for a direct…

Measuring magic on a quantum processor

Salvatore F. E. Oliviero, Lorenzo Leone, Alioscia Hamma +1

Magic states are the resource that allows quantum computers to attain an advantage over classical computers. This resource consists in the deviation from a property called stabiliz…
