Satisfying Quantum Codes: Physics-Informed and Hardware-Aware Code Design with SAT Solvers
Ben DalFavero, William M. Watkins, Margarite L. LaBorde +4
Although quantum error correction is widely believed to be necessary for impactful applications of quantum computers, the design of quantum error correction codes is largely done b…
Improving Dynamical Decoupling for Trapped-Ion QCCD Quantum Computers
William M. Watkins, Leigh M. Norris, Ross Hutson +3
We examine the impact of scheduling errors on dynamical decoupling (DD) in trapped-ion quantum charge-coupled devices (QCCDs) and develop better strategies for reducing memory erro…
Performance limits of a quantum receiver for detecting phase-modulated communication signals
William M. Watkins, Leigh Norris, Paraj Titum
Quantum sensors are an ideal candidate for detecting weak electromagnetic signals because of their exceptional sensitivity and compact form factor. In this work, we analyze the per…
Non-Markovian Noise in Symmetry-Preserving Quantum Dynamics
William M. Watkins, Gregory Quiroz
In quantum dynamics, symmetries are vital for identifying and assessing conserved quantities that govern the evolution of a quantum system. When promoted to the open quantum system…
Quantum Privacy Aggregation of Teacher Ensembles (QPATE) for Privacy-preserving Quantum Machine Learning
William Watkins, Heehwan Wang, Sangyoon Bae +4
The utility of machine learning has rapidly expanded in the last two decades and presents an ethical challenge. Papernot et. al. developed a technique, known as Private Aggregation…
