Robust Hamiltonian engineering with subensemble control
Wenjie Gong, Matteo Votto, Soonwon Choi
We present a robust protocol to reshape interactions in a spin ensemble based on global control pulse sequences applied to multiple subensembles in parallel. This setting arises na…
Learning mixed quantum states in large-scale experiments
Matteo Votto, Marko Ljubotina, Cécilia Lancien +5
We present and test a protocol to learn the matrix-product operator (MPO) representation of an experimentally prepared quantum state. The protocol takes as an input classical shado…
Universal quantum processors in spin systems via robust local pulse sequences
Matteo Votto, Johannes Zeiher, Benoît Vermersch
We propose a protocol to realize quantum simulation and computation in spin systems with long-range interactions. Our approach relies on the local addressing of single spins with e…
Entanglement phase diagrams from partial transpose moments
Jose Carrasco, Matteo Votto, Vittorio Vitale +5
We present experimentally and numerically accessible quantities that can be used to differentiate among various families of random entangled states. To this end, we analyze the ent…
Entanglement barrier and its symmetry resolution: theory and experiment
Aniket Rath, Vittorio Vitale, Sara Murciano +6
The operator entanglement (OE) is a key quantifier of the complexity of a reduced density matrix. In out-of-equilibrium situations, e.g. after a quantum quench of a product state,…
