Magic and Wormholes in the Sachdev-Ye-Kitaev Model
Valérie Bettaque, Brian Swingle
Any quantum state is fully specified by the expectation values of a complete set of Hermitian operators. For a system of Majorana fermions, such as the Sachdev-Ye-Kitaev (SYK) mode…

The Structure of the Majorana Clifford Group
Valérie Bettaque, Brian Swingle
In quantum information science, Clifford operators and stabilizer codes play a central role for systems of qubits (or qudits). In this paper, we study their analogues for systems c…

NoRA: A Tensor Network Ansatz for Volume-Law Entangled Equilibrium States of Highly Connected Hamiltonians
Valérie Bettaque, Brian Swingle
Motivated by the ground state structure of quantum models with all-to-all interactions such as mean-field quantum spin glass models and the Sachdev-Ye-Kitaev (SYK) model, we propos…
