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…

Lindblad-like quantum tomography for non-Markovian quantum dynamical maps
Santiago Varona, Markus Müller, Alejandro Bermudez
We introduce Lindblad-like quantum tomography (LQT) as a quantum characterization technique of time-correlated noise in quantum information processors. This approach enables…

Towards quantum computing Feynman diagrams in hybrid qubit-oscillator devices
S. Varona, S. Saner, O. BÄzÄvan +3
We show that recent experiments in hybrid qubit-oscillator devices that measure the phase-space characteristic function of the oscillator via the qubit can be seen through the lens…
