Information Scrambling and the Correspondence of Entanglement- and Operator Dynamics in Systems with Nonlocal Interactions
Darvin Wanisch, Juan Diego Arias Espinoza, Stephan Fritzsche
How fast quantum information scrambles such that it becomes inaccessible by local probes turns out to be central to various fields. Motivated by recent works on spin systems with n…
Engineering spin-spin interactions with optical tweezers in trapped ions
Juan Diego Arias Espinoza, Matteo Mazzanti, Katya Fouka +5
We propose a new method for generating programmable interactions in one- and two-dimensional trapped-ion quantum simulators. Here we consider the use of optical tweezers to enginee…
A high-fidelity method for a single-step -bit Toffoli gate in trapped ions
Juan Diego Arias Espinoza, Koen Groenland, Matteo Mazzanti +2
Conditional multi-qubit gates are a key component for elaborate quantum algorithms. In a recent work, Rasmussen et al. (Phys. Rev. A 101, 022308) proposed an efficient single-step…
