Numerical optimization of amplitude-modulated pulses in microwave-driven entanglement generation

M. Duwe, G. Zarantonello, N. Pulido-Mateo +7

Microwave control of trapped ions can provide an implementation of high-fidelity two-qubit gates free from errors induced by photon scattering. Furthermore, microwave conductors ma…

Boundary theories of critical matchgate tensor networks

Alexander Jahn, Marek Gluza, Charlotte Verhoeven +2

Key aspects of the AdS/CFT correspondence can be captured in terms of tensor network models on hyperbolic lattices. For tensors fulfilling the matchgate constraint, these have prev…

The time traveler's guide to the quantization of zero modes

Ana Alonso-Serrano, Erickson Tjoa, Luis J. Garay +1

We study the relationship between the quantization of a massless scalar field on the two-dimensional Einstein cylinder and in a spacetime with a time machine. We find that the latt…

Approaching the motional ground state of a 10 kg object

Chris Whittle, Evan D. Hall, Sheila Dwyer +197

The motion of a mechanical object -- even a human-sized object -- should be governed by the rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult: th…

Quantum Variational Optimization of Ramsey Interferometry and Atomic Clocks

Raphael Kaubruegger, Denis V. Vasilyev, Marius Schulte +2

We discuss quantum variational optimization of Ramsey interferometry with ensembles of entangled atoms, and its application to atomic clocks based on a Bayesian approach to pha…
