Entanglement spectrum of matchgate circuits with universal and non-universal resources
Entanglement spectrum of matchgate circuits with universal and non-universal resources
The entanglement level statistics of a quantum state have recently been proposed to be a signature of universality in the underlying quantum circuit. This is a consequence of level repulsion in the entanglement spectra being tied to the integrability of entanglement generated. However, such studies of the level-spacing statistics in …
