The magic cost of fermionic randomness
Chenfeng Cao, Yifan Tang, Jens Eisert
Sampling-based quantum advantage raises a basic resource question: how much non-Gaussianity is needed to reproduce the random-matrix statistics often associated with quantum chaos?…

Measurement-induced non-commutativity in adaptive fermionic linear optics
Chenfeng Cao, Yifan Tang, Jens Eisert
Fermionic linear optics (FLO) with Gaussian resources is known to be efficiently classically simulable. We show that this changes for fermions with internal degrees of freedom once…
