Hierarchically discriminating Haar-randomness in quantum states from a black-box device

Xavier Bonet-Monroig, Hao Wang, Adrián Pérez-Salinas

The concept of randomness in quantum computing has been central to constructing benchmarking tools, cryptographic protocols, as well as a proof of beyond-classical computation. Dis…

Universal approximation of continuous functions with minimal quantum circuits

Adrián Pérez-Salinas, Mahtab Yaghubi Rad, Alice Barthe +1

The conventional paradigm of quantum computing is discrete: it utilizes discrete sets of gates to realize bitstring-to-bitstring mappings, some of them arguably intractable for cla…
