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…
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…
Entanglement Scaling and Problem Structure in Quantum Approximate and Adiabatic Optimization Algorithms
Georgios Arapantonis, Paraj Titum, Gregory Quiroz
Entanglement is widely regarded as a key resource underlying the power of quantum algorithms and their potential to achieve quantum advantage. With the emergence of variational qua…
Assessing Spatiotemporally Correlated Noise in Superconducting Qubits via Pulse-Based Quantum Noise Spectroscopy
Mayra Amezcua, Leigh Norris, Tom Gilliss +4
Spatiotemporally correlated errors are widespread in quantum devices and are particularly adversarial to error correcting schemes. To characterize these errors, we propose and vali…
Quantum Noise Suppression at Scale with Crosstalk-Robust Gate Sets
Andy J. Goldschmidt, Emilio Peláez Cisneros, Ryan Sitler +3
We introduce crosstalk-robust gate sets, which are obtained using a novel, scalable optimal control problem exploiting locality. Through the suppression of pairwise quantum crossta…
Towards Predictive Quantum Algorithmic Performance: Modeling Time-Correlated Noise at Scale
Amit Jamadagni, Gregory Quiroz, Eugene Dumitrescu
Combining tensor network techniques with quantum autoregressive moving average models, we quantify the effects of time-correlated noise on quantum algorithms and predict their perf…
Quantum Optimization with Classical Chaos
Malick A. Gaye, Omar Shehab, Paraj Titum +1
The Quantum Approximate Optimization Algorithm (QAOA) is a powerful tool in solving various combinatorial problems such as Maximum Satisfiability and Maximum Cut. Hard computationa…
Crosstalk-Robust Dynamical Decoupling for Bipartite-Topology Quantum Processors
Ethan Hickman, Xiaodi Wu, Gregory Quiroz
We introduce a protocol that modifies dynamical decoupling (DD) sequences to be robust to static crosstalk when implemented with bounded control on two-colorable qubit topolog…
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…
Sparse Non-Markovian Noise Modeling of Transmon-Based Multi-Qubit Operations
Yasuo Oda, Kevin Schultz, Leigh Norris +2
The influence of noise on quantum dynamics is one of the main factors preventing current quantum processors from performing accurate quantum computations. Sufficient noise characte…
Model-Based Qubit Noise Spectroscopy
Kevin Schultz, Christopher A. Watson, Andrew J. Murphy +2
Qubit noise spectroscopy (QNS) is a valuable tool for both the characterization of a qubit's environment and as a precursor to more effective qubit control to improve qubit fidelit…
Mitigating Errors in DC Magnetometry via Zero-Noise Extrapolation
John S. Van Dyke, Zackary White, Gregory Quiroz
Zero-noise extrapolation (ZNE), a technique to estimate quantum circuit expectation values through noise scaling and extrapolation, is well-studied in the context of quantum comput…
Dynamically Generated Decoherence-Free Subspaces and Subsystems on Superconducting Qubits
Gregory Quiroz, Bibek Pokharel, Joseph Boen +7
Decoherence-free subspaces and subsystems (DFS) preserve quantum information by encoding it into symmetry-protected states unaffected by decoherence. An inherent DFS of a given exp…
Demonstration of Algorithmic Quantum Speedup for an Abelian Hidden Subgroup Problem
P. Singkanipa, V. Kasatkin, Z. Zhou +2
Simon's problem is to find a hidden period (a bitstring) encoded into an unknown 2-to-1 function. It is one of the earliest problems for which an exponential quantum speedup was pr…
