Observation of a topological edge state among localized bulk states in the anisotropic quantum Rabi model
Sungjoo Lim, Chanyang Im, Christopher G. Yale +7
Topological phases are governed by discrete symmetries that protect boundary modes against local perturbations. When translational periodicity is absent, the bulk states also becom…
Trigonometric Continuous-Variable Quantum Gates: Realization with Trapped Ions and Nonperturbative Wigner Negativity
Tommaso Rainaldi, Jake Montgomery, Christopher G. Yale +8
We experimentally realize trigonometric continuous-variable gates on a trapped-ion processor, for which a motional mode acquires a phase proportional to the cosine of its position…
Revealing Noise in Axial Motion Through Quantum Noise Spectroscopy on a Trapped Ion Processor
Vivian Maloney, Matthew Chow, Leigh Norris +7
Native noise processes in quantum processors are often difficult to isolate because multiple error mechanisms contribute to the same measured loss of coherence. Here we use dephasi…
QSCOUT's Qubit-Boson Gate Set
Edward C. Tortorici, Ethan C. McGarrigle, Brian K. McFarland +6
The Quantum Scientific Computing Open User Testbed (QSCOUT) has developed a qubit-boson gate set for hybrid continuous-discrete variable (CV-DV) quantum computing. This document ou…
High-performance gates on trapped ion qubits using counterpropagating pulse-shaped laser beams
Evangelos Piliouras, Hisham Amer, Susan M. Clark +9
Highly-localized light-matter interactions are necessary for scaling trapped-ion architectures. In hyperfine qubits, counterpropagating beams generate entangling gates by coupling…
Tensor-Network-Based Distributed Quantum Dynamics on Independent Quantum Computers
Anurag Dwivedi, Melissa C. Revelle, Daniel S. Lobser +6
We present an approach based on tensor networks for distributed quantum computing simulation of chemical wavepacket dynamics in a continuous variable representation. The central id…
Data-driven learning of non-Markovian quantum dynamics
Samuel Goodwin, Brian K. McFarland, Manuel H. Muñoz-Arias +6
Fault-tolerant quantum computing requires extremely precise knowledge and control of qubit dynamics during the application of a gate. We develop a data-driven learning protocol for…
Realization and Calibration of Continuously Parameterized Two-Qubit Gates on a Trapped-Ion Quantum Processor
Christopher G. Yale, Ashlyn D. Burch, Matthew N. H. Chow +5
Continuously parameterized two-qubit gates are a key feature of state-of-the-art trapped-ion quantum processors as they have favorable error scalings and show distinct improvements…
Solovay Kitaev Algorithm and Randomized Compilation
Oliver Maupin, Ashlyn D. Burch, Christopher G. Yale +10
We analyze the use of the Solovay Kitaev (SK) algorithm to generate an ensemble of one qubit rotations over which to perform randomized compilation. We perform simulations to compa…
Noise-Aware Circuit Compilations for a Continuously Parameterized Two-Qubit Gateset
Christopher G. Yale, Rich Rines, Victory Omole +9
State-of-the-art noisy-intermediate-scale quantum (NISQ) processors are currently implemented across a variety of hardware platforms, each with their own distinct gatesets. As such…
First-Order Crosstalk Mitigation in Parallel Quantum Gates Driven With Multi-Photon Transitions
Matthew N. H. Chow, Christopher G. Yale, Ashlyn D. Burch +4
We demonstrate an order of magnitude reduction in the sensitivity to optical crosstalk for neighboring trapped-ion qubits during simultaneous single-qubit gates driven with individ…
