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…
Stabilizer rank bounds for magic-state orbits
Farrokh Labib, Vincent Russo
Distinct Clifford orbits of magic states can exhibit different stabilizer ranks at small tensor powers. We establish this for qutrits, where the single-qutrit Clifford group has fo…
Opportunities and challenges in scaling quantum error detection on hardware
Yanis Le Fur, Ethan Egger, Hong-Ye Hu +3
Quantum error detection can produce unbiased expectation values that exponentially converge to noiseless results as the code distance is increased. Despite this, its performance as…
Compressed Sensing for Efficient Fidelity Estimation of GHZ States
Farrokh Labib, David Nicholaeff, Vincent Russo +1
Accurately characterizing multipartite entangled states is a critical challenge in quantum information processing. In this work, we focus on applying compressed sensing techniques…
Distinguishability of locally diagonal orthogonally invariant quantum states
Nathaniel Johnston, Vincent Russo
We study the distinguishability of quantum states under local operations with classical communication (LOCC), separable, and positive-partial-transpose (PPT) measurements, focusing…
Local strategies are pretty good at computing Boolean properties of quantum sequences
Tathagata Gupta, Ankith Mohan, Shayeef Murshid +3
Quantum memory is a scarce and costly resource, yet little is known about which learning tasks remain feasible under severe memory constraints. We study the problem of computing gl…
