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…

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…
