Reconstructing complex states of a 20-qubit quantum simulator
Murali K. Kurmapu, V. V. Tiunova, E. S. Tiunov +6
A prerequisite to the successful development of quantum computers and simulators is precise understanding of physical processes occurring therein, which can be achieved by measurin…
Native qudit entanglement in a trapped ion quantum processor
Pavel Hrmo, Benjamin Wilhelm, Lukas Gerster +6
Quantum information carriers, just like most physical systems, naturally occupy high-dimensional Hilbert spaces. Instead of restricting them to a two-level subspace, these high-dim…
Experimental single-setting quantum state tomography
Roman Stricker, Michael Meth, Lukas Postler +7
Quantum computers solve ever more complex tasks using steadily growing system sizes. Characterizing these quantum systems is vital, yet becoming increasingly challenging. The gold-…
Theory of phase-adaptive parametric cooling
Alekhya Ghosh, Pardeep Kumar, Fidel Jimenez +2
We propose an adaptive phase technique for the parametric cooling of mechanical resonances. This involves the detection of the mechanical quadratures, followed by a sequence of per…
Approaching optimal entangling collective measurements on quantum computing platforms
Lorcan O. Conlon, Tobias Vogl, Christian D. Marciniak +9
Entanglement is a fundamental feature of quantum mechanics and holds great promise for enhancing metrology and communications. Much of the focus of quantum metrology so far has bee…
Probing phases of quantum matter with an ion-trap tensor-network quantum eigensolver
Michael Meth, Viacheslav Kuzmin, Rick van Bijnen +7
Tensor-Network (TN) states are efficient parametric representations of ground states of local quantum Hamiltonians extensively used in numerical simulations. Here we encode a TN an…
