Sample-efficient verification of continuously-parameterized quantum gates for small quantum processors

Ryan Shaffer, Hang Ren, Emiliia Dyrenkova +7

Most near-term quantum information processing devices will not be capable of implementing quantum error correction and the associated logical quantum gate set. Instead, quantum cir…

Quantum simulation of weak-field light-matter interactions

Steve M. Young, Hartmut Häffner, Mohan Sarovar

Simulation of the interaction of light with matter, including at the few-photon level, is important for understanding the optical and optoelectronic properties of materials, and fo…

Trapped electrons and ions as particle detectors

Daniel Carney, Hartmut Häffner, David C. Moore +1

Electrons and ions trapped with electromagnetic fields have long served as important high-precision metrological instruments, and more recently have also been proposed as a platfor…

Changes in electric-field noise due to thermal transformation of a surface ion trap

Maya Berlin-Udi, Clemens Matthiesen, P. N. Thomas Lloyd +9

We aim to illuminate how the microscopic properties of a metal surface map to its electric-field noise characteristics. In our system, prolonged heat treatments of a metal film can…

Distance scaling and polarization of electric-field noise in a surface ion trap

Da An, Clemens Matthiesen, Erik Urban +1

We probe electric-field noise in a surface ion trap for ion-surface distances between 50 and 300 in the normal and planar directions. We find the noise distance d…

Improved Test of Local Lorentz Invariance from a Deterministic Preparation of Entangled States

Eli Megidish, Joseph Broz, Nicole Greene +1

The high degree of control available over individual atoms enables precision tests of fundamental physical concepts. In this Letter, we experimentally study how precision measureme…
