Simulation of noisy quantum circuits using frame representations
Janek Denzler, Jose Carrasco, Jens Eisert +1
One of the core research questions in the theory of quantum computing is to find out to what precise extent the classical simulation of a noisy quantum circuits is possible and whe…

Highly-entangled, highly-doped states that are efficiently cross-device verifiable
Janek Denzler, Santiago Varona, Tommaso Guaita +1
In this paper, we introduce a class of highly entangled real quantum states that cannot be approximated by circuits with -many non-Clifford gates and prove that Bell sampling…

Learning fermionic correlations by evolving with random translationally invariant Hamiltonians
Janek Denzler, Antonio Anna Mele, Ellen Derbyshire +2
Schemes of classical shadows have been developed to facilitate the read-out of digital quantum devices, but similar tools for analog quantum simulators are scarce and experimentall…
