Nonstabilizerness of quantum tensor network states is intractable in two dimensions
Gianluca Esposito, Georgios Styliaris
Nonstabilizerness is a necessary resource for quantum systems to lie beyond the classically simulable regime. With the advent of stabilizer -Rényi entropies, nonstabilizerness h…
Stabilizer entropy is trustworthy for mixed states
Gianluca Esposito, Michele Viscardi, Alioscia Hamma
Quantifying non-stabilizerness in mixed states is provably intractable, as any strict monotone requires superexponential time. We propose a linear Stabilizer Entropy that acts as a…
Probes of chaos over the Clifford group and approach to Haar values
Stefano Cusumano, Gianluca Esposito, Alioscia Hamma
Chaotic behavior of quantum systems can be characterized by the adherence of the expectation values of given probes to moments of the Haar distribution. In this work, we analyze th…
