Entanglement-magic separation in hybrid quantum circuits
Gerald E. Fux, Emanuele Tirrito, Marcello Dalmonte +1
Magic describes the distance of a quantum state to its closest stabilizer state. It is -- like entanglement -- a necessary resource for a potential quantum advantage over classical…
Measurement-induced transitions beyond Gaussianity: a single particle description
Luca Lumia, Emanuele Tirrito, Rosario Fazio +1
Repeated measurements can induce entanglement phase transitions in the dynamics of quantum systems. Interacting models, both chaotic and integrable, generically show a stable volum…
Many-body magic via Pauli-Markov chains -- from criticality to gauge theories
Poetri Sonya Tarabunga, Emanuele Tirrito, Titas Chanda +1
We introduce a method to measure many-body magic in quantum systems based on a statistical exploration of Pauli strings via Markov chains. We demonstrate that sampling such Pauli-M…
Emergence of non-Abelian SU(2) invariance in Abelian frustrated fermionic ladders
Bachana Beradze, Mikheil Tsitsishvili, Emanuele Tirrito +3
We consider a system of interacting spinless fermions on a two-leg triangular ladder with magnetic flux per triangular plaquette. Microscopically, the system exhibits a U(1)…
Quantifying non-stabilizerness through entanglement spectrum flatness
Emanuele Tirrito, Poetri Sonya Tarabunga, Gugliemo Lami +6
Non-stabilizerness - also colloquially referred to as magic - is the a resource for advantage in quantum computing and lies in the access to non-Clifford operations. Developing a c…
