Pseudomagic Quantum States
Andi Gu, Lorenzo Leone, Soumik Ghosh +3
Notions of nonstabilizerness, or "magic", quantify how non-classical quantum states are in a precise sense: states exhibiting low nonstabilizerness preclude quantum advantage. We i…
Learning t-doped stabilizer states
Lorenzo Leone, Salvatore F. E. Oliviero, Alioscia Hamma
In this paper, we present a learning algorithm aimed at learning states obtained from computational basis states by Clifford circuits doped with a finite number of -gates. T…
Stabilizer entropy dynamics after a quantum quench
Davide Rattacaso, Lorenzo Leone, Salvatore F. E. Oliviero +1
Stabilizer entropies (SE) measure deviations from stabilizer resources and as such are a fundamental ingredient for quantum advantage. In particular, the interplay of SE and entang…
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…
Phase transition in Stabilizer Entropy and efficient purity estimation
Lorenzo Leone, Salvatore F. E. Oliviero, Gianluca Esposito +1
Stabilizer Entropy (SE) quantifies the spread of a state in the basis of Pauli operators. It is a computationally tractable measure of non-stabilizerness and thus a useful resource…
