Interaction graph engineering in trapped-ion quantum simulators with global drives
Antonis Kyprianidis, A. J. Rasmusson, Philip Richerme
Trapped-ion quantum simulators have demonstrated a long history of studying the physics of interacting spin-lattice systems using globally addressed entangling operations. Here, we…
QDoor: Exploiting Approximate Synthesis for Backdoor Attacks in Quantum Neural Networks
Cheng Chu, Fan Chen, Philip Richerme +1
Quantum neural networks (QNNs) succeed in object recognition, natural language processing, and financial analysis. To maximize the accuracy of a QNN on a Noisy Intermediate Scale Q…
An open-endcap blade trap for radial-2D ion crystals
Yuanheng Xie, Jiafeng Cui, Marissa D'Onofrio +3
We present the design and experimental demonstration of an open-endcap radio frequency trap to confine ion crystals in the radial-two dimensional (2D) structural phase. The central…
Susceptibility of Trapped-Ion Qubits to Low-Dose Radiation Sources
Jiafeng Cui, A. J. Rasmusson, Marissa D'Onofrio +3
We experimentally study the real-time susceptibility of trapped-ion quantum systems to small doses of ionizing radiation. We expose an ion-trap apparatus to a variety of , ,…
Radial two-dimensional ion crystals in a linear Paul trap
Marissa D'Onofrio, Yuanheng Xie, A. J. Rasmusson +3
We experimentally study two-dimensional (2D) Coulomb crystals in the "radial-2D" phase of a linear Paul trap. This phase is identified by a 2D ion lattice aligned entirely with the…
Cryogenic Trapped-Ion System for Large Scale Quantum Simulation
G. Pagano, P. W. Hess, H. B. Kaplan +9
We present a cryogenic ion trapping system designed for large scale quantum simulation of spin models. Our apparatus is based on a segmented-blade ion trap enclosed in a 4 K cryost…
