Non-Abelian String-Breaking Dynamics on a Qudit Quantum Computer
Manuel John, Keshav Pareek, Peter Tirler +7
Gauge theories form the foundation of the Standard Model of particle physics. These theories can exhibit confinement, where charged particles only occur in bound states, connected…
Radio-Frequency Side-Channel Analysis of a Trapped-Ion Quantum Computer
Giorgio Grigolo, Dorian Schiffer, Lukas Gerster +2
Analogously to classical computers, quantum processors exhibit side channels that may give attackers access to potentially proprietary algorithms. We identify and exploit a previou…
Device-independent quantum memory certification in two-point measurement experiments
Leonardo S. V. Santos, Peter Tirler, Michael Meth +6
Quantum memories are key components of emerging quantum technologies. They are designed to store quantum states and retrieve them on demand without losing features such as superpos…
Experimental realization of nonunitary multi-qubit operations
Martin W. van Mourik, Elias Zapusek, Pavel Hrmo +5
We demonstrate a novel experimental toolset that enables irreversible multi-qubit operations on a quantum platform. To exemplify our approach, we realize two elementary nonunitary…
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…
Analytical and experimental study of center line miscalibrations in Mølmer-Sørensen gates
Fernando Martínez-García, Lukas Gerster, Davide Vodola +4
A major challenge for the realisation of useful universal quantum computers is achieving high fidelity two-qubit entangling gate operations. However, calibration errors can affect…
Experimental Bayesian calibration of trapped ion entangling operations
Lukas Gerster, Fernando Martínez-García, Pavel Hrmo +7
The performance of quantum gate operations is experimentally determined by how correct operational parameters can be determined and set, and how stable these parameters can be main…
RF-induced heating dynamics of non-crystallized trapped ions
Martin W. van Mourik, Pavel Hrmo, Lukas Gerster +4
We investigate the energy dynamics of non-crystallized (melted) ions, confined in a Paul trap. The non-periodic Coulomb interaction experienced by melted ions forms a medium for no…
Coherent rotations of qubits within a multi-species ion-trap quantum computer
Martin W. van Mourik, Esteban A. Martinez, Lukas Gerster +4
We describe, realize, and experimentally investigate a method to perform physical rotations of ion chains, trapped in a segmented surface Paul trap, as a building block for large s…
