Magic-protected entanglement and Clifford-irreducible structure in magic state space
Alejandro Borda Kuhlmann, Julian Rincon
We develop a Clifford-orbit framework for studying magic-protected entanglement, which we refer to as magical entanglement: the part of bipartite entanglement that remains after op…

Quantum Universality in Composite Systems: A Trichotomy of Clifford Resources
Alejandro Borda, Julian Rincon, César Galindo
We show that single-qudit universality in Clifford-based gate sets follows a trichotomy determined by the prime factorization of the local dimension . For prime , any gate ou…

Universal quasi-Fermi liquid physics of one-dimensional interacting fermions
Joshua D. Baktay, Adrian E. Feiguin, Julian Rincon
We present a class of one-dimensional generic spinless fermion lattice Hamiltonians that express quasi-Fermi liquid physics, manifesting both Luttinger and Fermi liquid features du…
