Clifford entropy
Gianluca Cuffaro, Matthew B. Weiss
We introduce the Clifford entropy, a measure of how close an arbitrary unitary is to a Clifford unitary, which generalizes the stabilizer entropy for states. We show that this quan…
Stabilizer Entropy of Subspaces
Simone Cepollaro, Gianluca Cuffaro, Matthew B. Weiss +3
We consider the costs and benefits of embedding the states of one quantum system within those of another. Such embeddings are ubiquitous, e.g., in error correcting codes and in sym…
Quantum States with Maximal Magic
Gianluca Cuffaro, Christopher A. Fuchs
Finding ways to quantify magic is an important problem in quantum information theory. Recently Leone, Oliviero and Hamma introduced a class of magic measures for qubits, the stabil…
Stabilizer entropy of quantum tetrahedra
Simone Cepollaro, Goffredo Chirco, Gianluca Cuffaro +2
How complex is the structure of quantum geometry? In several approaches, the spacetime atoms are obtained by the SU(2) intertwiner called quantum tetrahedron. The complexity of thi…
Curvature from multipartite entanglement in quantum gravity states
Simone Cepollaro, Goffredo Chirco, Gianluca Cuffaro +1
We investigate the multipartite entanglement of a uniformly curved quantum 3D space region with boundary, realised in terms of spin networks defined on a graph with non trivial SU(…
Entanglement Negativity on Random Spin Networks
Goffredo Chirco, Simone Cepollaro, Gianluca Cuffaro +1
We investigate multipartite entanglement for quantum states of 3d space geometry, described via generalised random spin networks with fixed areas, in the context of background inde…
