Topological magic response in quantum spin chains
Ritu Nehra, Poetri Sonya Tarabunga, Martina Frau +3
Topological matter provides natural platforms for robust, non-local information storage, central to quantum error correction. Yet, while the relation between entanglement and topol…
Nonstabilizerness in U(1) lattice gauge theory
Pedro R. Nicácio Falcão, Poetri Sonya Tarabunga, Martina Frau +3
We present a thorough investigation of nonstabilizerness - a fundamental quantum resource that quantifies state complexity within the framework of quantum computing - in a one-dime…
Stabilizer disentangling of conformal field theories
Martina Frau, Poetri Sonya Tarabunga, Mario Collura +2
Understanding how entanglement can be reduced through simple operations is crucial for both classical and quantum algorithms. We investigate the entanglement properties of lattice…
A nonstabilizerness monotone from stabilizerness asymmetry
Poetri Sonya Tarabunga, Martina Frau, Tobias Haug +2
We introduce a nonstabilizerness monotone which we name basis-minimised stabilizerness asymmetry (BMSA). It is based on the notion of -asymmetry, a measure of how much a certain…
